IRMD26310DJ www.irf.com ? 2008 international rectifier 6 IRMD26310DJ - hardware description the IRMD26310DJ reference design kit supports the e valuation of the irs26310dj which is a high voltage power mosfet and igbt driver with integrated dc bus overv oltage protection. the reference design is a full-f unction unit operating out of 220vac input. an onboard digi tal controller ic enables driving an induction moto r in open- loop volts-per-hertz mode. the included gui softwar e allows modification of system parameters in order to drive an induction motor in open-loop volts-per-hertz mod e and study the irs26310dj high voltage gate driver ic by changing parameters such as pwm frequency and deadt ime. in addition to dc bus overvoltage protection offered by irs26310dj, the reference design is equi pped with protection against motor line-to-line and line-to-dc bus(-) short by way of irs26310dj itrip function an d also a gui software controlled motor current limi t. the board includes multiple test points to facilitate m onitoring irs26310dj input and output signal wavefo rms and examining its various features. top level description the IRMD26310DJ reference design is composed of the following key blocks: ? the input stage includes an emi filter, 8a bridge rectifier and dc bus capacitor rated for 400w conti nuous operation. it is noted that IRMD26310DJ does not fe ature a current limiting fuse. ? the power inverter uses 6 x irgib10k60d1 igbt powe r switches mounted on a 1.9 o c/w heatsink. the igbts can be replaced with user preferred power dev ices but user may need to replace components such as bridge rectifier & dc bus current shunt to match the device ratings. ? the igbts in the power inverter stage are driven b y the irs26310dj gate driver and associated circuit ry involving bootstrap capacitors, gate drive timing r esistors, and fault diagnostic elements. ? the control circuitry for driving the motor is bas ed on the irmcf341 digital control ic. the irmcf341 control ic has been configured to run an induction motor in the open-loop volts-per-hertz mode. the control ic generates the pwm signals for irs26310dj gate driver. the user also has the option to drive the irs26310dj externally by disconnecting the jump ers on connector p1 and bridging in external connections. the digital ic communicates with a pc over an isolated serial link and the included gui software allows the user to set the motor speed and modify common inverter parameters such as switching frequency and deadtime. ? an on-board dc-dc converter low voltage power supp ly derives the 15v, 3.3v & 1.8v rails from the main dc bus. for more information regarding the other blocks of the reference design, please refer to the detailed schematics. figure 1: IRMD26310DJ system block diagram
IRMD26310DJ www.irf.com ? 2008 international rectifier 7 figure 2: picture of IRMD26310DJ reference design irs26310dj gate driver ic the irs26310dj ic integrates three independent half bridge drivers with shoot through protection and i nternal dead-time insertion. proprietary hvic technology en ables ruggedized monolithic construction with logic inputs compatible with cmos or lsttl levels as low as 3.3 v. the output drivers feature a high pulse current buffer stage designed for minimum driver cross-conduction. propagation delays are matched to simplify use in high frequency applications. the floating channel can be used to drive n-channel power mosfets or igbts in the high side configuration, which operates up to 600v. the ic is based on ?active high? input logic i.e. a logic high input turns on the corresponding output and vice ve rsa. in addition to vss pin, the ic features a com pin to provide a dedicated, low impedance return path for the low side gate driver which also serves to shunt the high- frequency gate drive currents away from the current sense resistor thus preventing false trips. the ic provides dc bus capacitor protection by activating zero-vect or motor braking whenever an overvoltage condition is sensed. this feature should only be used with motor s that can withstand short-term short circuit of th e motor windings. other protection features offered by the ic include uvlo for vcc & vbs supplies and motor cu rrent trip along with integrated fault diagnostics are al so offered in irs26310dj. an open-drain fault signa l is provided to indicate that an over-current or a vcc under-voltage shutdown has occurred. an enable func tion integrated into the fault/ pin allowing the user to terminate all six outputs simultaneously. figure 3: irs26310dj application diagram input stage power inverter gate driver circuitry connector for external pwm drive dc-dc converter control circuitry power connector pc connector input stage power inverter gate driver circuitry connector for external pwm drive dc-dc converter control circuitry power connector pc connector
IRMD26310DJ www.irf.com ? 2008 international rectifier 8 bootstrap supply the floating high side driver supplies are generate d by a bootstrap circuit as shown in figure 4. the ic turns on the internal ?bootfet? when the low side transistor is on to charge up the bootstrap capacitor (c boot ). the ?bootfet? eliminates the requirement for an externa l boot diode d boot as is the case for previous generation gate drivers. an application note an-1123 ( http://www.irf.com/technical-info/appnotes/an-1123. pdf ) describes the selection of the bootstrap capacitor and considerat ions when using the internal bootfet. in some cases , an external bootstrap circuit may be preferable. the i rmd26310dj board also provides option for external bootstrap supply. this can be invoked by populating the boots trap resistor, r boot (r17) and bootstrap diodes (d6, d7 & d8). the bootstrap capacitors must be fully charged to a void missing high side pulses due to under voltage lockout on the floating high side supply. the digital controll er on the board pre-charges the capacitors by turni ng on the low side transistors for a short period before starting to run the motor. the charging current and time de pends on the resistance of the internal bootfet or the external boot resistance. typically, the pre-charge sequence charges the capacitors one at a time to avoid spurious over current trips since the charging current flows thr ough the current sensing shunt. figure 4: bootstrap circuit gate drive resistors the IRMD26310DJ board has gate resistor networks to allow fine tuning of the power switch turn on and turn off times. figure shows the gate circuit schematic while table 1 lis t the resistors used in the network for each power device. figure 5: gate circuit u v w high side gate (ho turn-on/off) r61/r99/d9 r62/r101 /d10 r63/r118/d11 low side gate (lo turn-on/off) r64/r119/d12 r65/r12 0/d13 r66/r121/d14 table 1: gate drive circuit components
IRMD26310DJ www.irf.com ? 2008 international rectifier 9 IRMD26310DJ protection features motor overcurrent protection motor over-current protection is implemented using a dc link shunt resistor (r60) placed between power ground (com pin) and logic ground (vss pin) as shown in fi gure 6. the itrip signal from the shunt has an inpu t rc filter (r38, c37) to reject power inverter noise. t he irs26310d has a comparator that generates a shut down signal when the itrip pin voltage exceeds the itrip threshold (v it,th+ ). an internal noise filter rejects pulses shorter than 400ns to avoid spurious trips due to d iode reverse recovery current. the shutdown signal turns off all six outputs and pulls the en fault / pin low. when the over-current condition is cleared , the fault remains latched until reset by the voltage on the rcin. under-voltage protection circuits the ic monitors the supply voltage on the v cc pin. it turns off all six outputs and pulls the en fault / pin low when v cc falls below a minimum threshold (v ccuv- ). this fault is not latched but is cleared once v cc goes above the positive going threshold (v ccuv+ ). the ic also features uvlo protection for all 3 v bs floating supplies; however, a vbs uvlo condition does not trigger fault reporti ng i.e. en fault / pin is not pulled low. under a vbs uvlo condition, only the corresponding gate driver outpu t is terminated until the vbs uvlo condition is cle ared. dc bus over-voltage protection circuits the irs26310d monitors the dc bus to prevent it cha rging to an unsafe voltage level during regenerativ e braking. the divider network r35, r36 and r37 drops the dc b us to a low voltage level and communicates to irs26310d. a comparator and noise filter detects a bus over-voltage condition when the voltage on the dcbussense pin goes above a maximum threshold (v dcbusov+ ). the default resistor divider configuration in IRMD26310DJ will trigger irs26310dj dc bus overvolt age protection feature at approximately 386v. when an over-voltage condition is sensed, it forces irs26310dj into zero vector mode, which turns on a ll low side transistors and turns off all high side transi stors irrespective of the pwm input commands from d igital control ic. irs26310dj then returns to normal operating mod e when the voltage on the dcbussense pin drops belo w a minimum threshold (v dcbusov ). the dc bus over-voltage state is not reported on the en fault / pin. for more information regarding how to trigger the dc bus ove rvoltage protection feature, please refer to ?operating instructions? section. IRMD26310DJ fault reporting the en fault / pin of the ic is used to communicate a fault situat ion to the digital control ic (dcic). the en fault / pin, which is normally pulled up to 3.3v using pull up resistor, is connected to the gatekill pin on t he irmcf341. when the ic detects a fault situation (ei ther due to vcc uvlo or itrip) all gate driver outp uts are shut-down and the en fault / pin is pulled low and this triggers the gatekill fu nction of irmcf341 causing all pwm outputs of irmcf341 to be shutdown. fault repor ting is performed only for the following: - motor overcurrent (itrip) - vcc supply uvlo it is again noted that vbs uvlo & dc bus overvoltag e situations do not trigger a fault situation. automatic reset after itrip fault automatic fault reset provided by the hvic is based on the time constant (rc reset ) of the passive network on the rcin pin. an rc network (r39, c38) between the rcin pin and vcc supply allows an automatic reset of th e itrip fault. the capacitor on the rcin pin is held low as long as the itrip comparator input exceeds t he itrip voltage threshold. when the itrip fault condition c lears, the capacitor is allowed to charge up. the i trip fault is reset when the capacitor voltage exceeds a minimum threshold (v rcin,th+ ). the rcin auto-reset time can be calculated from the following equation: ? ?? ? ? ?? ? ? ? = + rcinth cc cc v v v c r t ln 38 39 the reference design auto reset time is approximate ly 1.6ms for v cc =15v, v rcinth+= 8v and r 39 =2mohm, c 38 =1nf. the on resistance of the reset fet on the rcin pin cannot be neglected so a relatively small capacitor should be used so that it becomes fully discharged before the fault is released.
IRMD26310DJ www.irf.com ? 2008 international rectifier 10 irmd26310 enable function the ic features an enable function integrated into the en fault / pin to provide enable/disable functionality. the ic functionality is enabled when en pin is biased h igh. in the IRMD26310DJ reference design, the en fault / pin is pulled up to 3.3v dc bus using resistor r28 pote ntial to always enable operation. figure 6: protection circuits, fault reporting & au tomatic reset after itrip fault pwm input to irs26310dj & connection of an external system controller IRMD26310DJ is configured by default to use the pwm signals from the on-board irmcf341 controller for the irs26310dj hvic. the default configuration con nects the irmcf341 digital control ic to the irs26310dj by shorting pins 5-6, 7-8, 9-10, 11-12, 13-14, 15-16, 17-18 on connector p1 shown in figure 7. since the irs26310dj is based on active high logic, the pwm inputs to the hvic in IRMD26310DJ are connected to gnd using pull-down resistors (r26 to r32). an external controller can easily be invoked for dr iving the irs26310j by removing the shorting connec tions on the 20 pins dil connector p1 and connecting the external pwm signals to the odd numbered pins on p1 . it is reiterated that the correct pwm inputs that i s appropriate for the ?active high? logic of irs263 10dj must be maintained. figure 7: 20-pin connector p1

IRMD26310DJ www.irf.com ? 2008 international rectifier 18 how to trigger irs26310dj dc bus overvoltage protec tion the irs26310d gate driver ic monitors the dc bus vo ltage to prevent it from charging to an unsafe volt age level during regenerative braking when used to driv e permanent magnet motors. the dc bus voltage is scaled down using a resistor divider and communicat ed to the dcbussense pin. when the voltage on the dcbussense pin goes above a maximum threshold (v dcbusov+ ) an over-voltage condition is sensed and it forces irs26310dj into zero vector mode. in this mo de the driver turns-on all low side transistors and turns- off all high side transistors irrespective of the p wm input commands from digital control ic. the divi der network r35, r36 and r37 in IRMD26310DJ sets dc bus overvoltage protection level to 386v. figure 18: irs26310 dc bus overvoltage protection fea ture since IRMD26310DJ will be used to drive an inductio n motor, which does not engage regenerative braking like a permanent magnet motor, it is not straightfo rward to trigger the dc bus overvoltage protection of the driver ic. however, the following suggestions are p rovided i. the decel rate parameter in software gui is used to define the ramp-down characteristic of the induction motor during halting. a smaller value hal ts the motor more abruptly. by engaging an abrupt s top of the induction motor when running at a high speed under loaded condition, it is possible to create a dc bus voltage overshoot during motor stop. zero vecto r insertion is triggered when the overshoot exceeds 386v. for more information regarding the decel rate parameter pl ease refer to ?software gui reference guide? section. further, by changing resistor r37, it is also poss ible to decrease the dc bus overvoltage level at which the protection is trigge red to suit other test conditions such as ac input voltage level, motor speed, load-under-test etc. for exampl e, in fig.19 where zero-vector insertion is activat ed during motor stop, the reference design was modifie d to trigger dc bus overvoltage protection feature at 275v. figure 19: zero vector insertion during irs26310dj dc bu s overvoltage protection ii. the dc bus overvoltage feature can also be enga ged in a ?static? test (motor not running) in order to verify the ic functionality. to do this the ac inpu t voltage level can simply be increased high enough to result in a rectified dc bus voltage greater than 3 86v; however, in this method, running the motor wil l not be possible since software gui will trigger a ?dc b us voltage level fault?. lo1 motor current dc bus voltage zoom-in zero-vector insertion & lo turn-on lo1 motor current dc bus voltage zoom-in zero-vector insertion & lo turn-on
