dspicdem? mchv development system user?s guide ? 2009 microchip technology inc. ds70605a-page 7 chapter 1. introduction 1.1 overview the microchip dspicdem? mchv development system is intended to aid the user in the rapid evaluation and development of a wide variety of motor control applications using a dspic ? digital signal controller (dsc). this development system is targeted to control brushless dc (bldc) motors, permanent magnet synchronous motors (pmsm), and ac induction motors (acim) in sensor or sensorless operation. this flexible and cost-effective tool can be configured in different ways for use with microchip?s specialized motor control dscs. the dspicdem? mchv development system supports the dspic33f motor control device family, and offers a mounting option to connect either a 28-pin soic device or a generic 100-pin plug-in module (pim). the system has a three-phase power module device that contains the motor inverter and the gate driver?s circuitry. the circuit drives a bldc, pmsm, or acim motor using different control techniques without requiring any additional hardware. it also has power factor correction (pfc) circuitry in order to provide a full set of tools used in motor control applications. figure 1-1 provides a photograph of the dspicdem? mchv development system. a block diagram that shows the main components of the system is provided in figure 1-2. the rated continuous output current from the inverter is 6.5a (rms). this allows up to approximately 2 kva output when running from a 208v to 230v single-phase input volt- age in a maximum 30oc (85of) ambient temperature environment. therefore, the sys- tem is ideally suited for running a standard 3-phase induction motor of up to 1.4 kw (1.8 hp) rating or a slightly higher rated industrial servo-motor. the power module is capable of driving other types of motors and electrical loads that do not exceed the maximum power limit and are predominantly inductive. furthermore, single-phase loads can be driven using one or two of the inverter outputs. the unit is capable of operating from 90v up to a maximum of 265v. a more detailed explanation of power limitations is provided in chapter 4. ?hardware? . note: it is recommended to carefully read the hardware section mentioned above before attempting to use the system.

dspicdem? mchv development system user?s guide ds70605a-page 30 ? 2009 microchip technology inc. 4.1.2 active power factor correction (pfc) the active pfc circuit is essentially a simple boost chopper with the control aimed at shaping the input current to follow the incoming mains supply waveform. the purpose of the different parts of the circuit is described below. ? l6 ? a high frequency axial inductor with a single layer winding on a ferrite core. this component is in series with the main inductor (l7) to reduce the effect of the self-capacitance of its winding. without l6, significant high frequency (15 mhz) ringing of the inductor current occurs at every transistor turn-on, which would increase emi and the pfc transistor switching loss. ? l7 ? a power inductor with three stacked toroidal cores made from a powdered-iron material to limit the core loss while maintaining good energy storage density. the particular cores used are magnetics 0077083a7. a simple multi-layer winding is used which results in moderate copper loss but significant self-capacitance. sixty-six turns of 1.5 mm diameter enameled copper wire is used. the design offers a good compromise between cost, core loss and size for this application. the nominal inductance is 1 mh at 10a. ? q2 ? a 600v to-247 igbt. as the tab of the device is not isolated, a thermally conductive insulator is used. when closed, q2 increase the energy stored in the inductor l7. when open, energy stored in the inductance is transferred to the dc bus capacitors (c30-c32). energy is also drawn from the ac supply during this time. by appropriate control of the switches, the input current waveform can be profiled to obtain good power factor and low harmonic distortion. ? d12 ? a 600v to-247 diode optimized for use at high switching frequency. as the tab of the device is not isolated, a thermally conductive insulator is used. ? c28, r31, r32, r33, d11 ? a ?snubber? that acts to damp high frequency oscillations and limit the rate of change of voltage across q2 ? c30, c31, c32 ? 470 f/450v electrolytic capacitors which act as the main dc bus energy storage capacitors. ? r25, r26, c25, d8, q1, r27, r28 ? a lever shifter to boost the pwm signal com- ing from the dspic dsc ? u19 ? microchip tc4421a gate drive ic. this contains a low resistance comple- mentary push-pull mosfet pair and input circuitry suitable for interfacing to a wide range of input voltages. it is an ideal choice for this application allowing up to 10a of peak gate drive current to switch q2 rapidly and therefore achieve low switching loss. it also has a small footprint allowing it to be located physically close to the transistors allowing a low inductance gate circuit layout. ? d9, c26, c27 ? these components act to provide a dynamic level shifting circuit to u19 while q2 switch. inductance of the power tracking between the source of q2 due to the physical board layout means there is a substantial transient voltage between the +15v supply point reference at r28 and the source of q2. this simple low cost circuit allows the power supply of u19 to move transiently. ? r75, r29 and d10 ? these components control the current and voltage to turn on and turn off the igbt. r29 controls the rising time and the di/dt when the igbt is turned on. r29 in parallel with r75 control the falling time and the di/dt when the igbt is turned off. ? the power factor corrector design is based on the application note an1106, for more information on this application note please refer to one of the following microchip web sites: - www.microchip.com/smps - www.microchip.com/dscmotor
hardware ? 2009 microchip technology inc. ds70605a-page 31 4.1.3 pfc feedback circuitry in a dsc-based pfc, the relevant analog parameters and the control loops need to be redefined and discretized. this enables changeover from existing hardware to its digital counterpart easier and more logical. the pfc is an ac-to-dc converter, which converts the ac input voltage to a dc volt- age and maintains sinusoidal input current at a high input power factor. in a dsc-based pfc, three inputs signals are required to implement the current control. the input rectifier (br1) converts (shown in section 4.1.1 ?ac supply input ? ) the alternating voltage at power frequency into unidirectional voltage. this rectified voltage is fed to the chopper circuit to produce a smooth and constant dc output voltage to the load. the chopper circuit is controlled by the pwm switching pulses generated by the dspic dsc device, based on three measured feedback signals: ? rectified input voltage ? ac input voltage zero-crossing event ? rectified input current ? dc bus voltage the rectified input voltage is measured in two stages: ? signal conditioning: r22, r23, r24, c24, and d7 convert and filter the ac input voltage waveform from 90-265 vac to 0-3.3 vac. d7 limit the maximum voltage to 3.3v. c24 along with r22, r23 form a low-pass filter. the circuit is shown in appendix a. ? amplification: the operational amplifier mcp6024 (u13b) amplifies the condi- tioned ac input voltage; r45, r46, r47, r48, r49 and r51 set the gain. the mc6024 also shifts the conditioned ac input voltage to a 1.65v dc level. there- fore, the voltage applied to the dspic dsc adc channel varies within 0-3.3v. the offset is controlled by r50, r53, and r54. r39 and c39 filter out the high-frequency noise. ac input voltage zero-crossing event is sensed using a voltage divider (r2-r5) and two opto-couplers (u1 and u2). the circuit is shown in appendix a. rectified input current is measured using the shunt resistor r34 and the operational amplifier mcp6024 (u13a); r38, r39, r40, r41, r42 and r43 set the gain. r43 shifts the voltage present at the shunt resistor to a 1.65v dc level. therefore, the voltage applied to the dspic dsc adc channel varies within 0-3.3v. the offset is controlled by r43, r53, and r54. r44 and c37 filter out the high-frequency noise. the circuit is shown in appendix a. dc bus voltage, the dc bus voltage is sensed at the power module stage. please refer to section 4.2.4 ?feedback circuitry? . 4.1.4 power supplies the pfc stage board provides the 15 volts power supply required to fire the power module igbts. the 15 volts power supply is built using a low power off-line smps pri- mary switcher. the switching frequency is fixed to 60 khz, the feedback signal to the power supply is provided by and opto-coupler. the output voltage is regulated at 15v with a maximum output current of 0.750 a, the resultant maximum power is 11.25 w. the input voltage range for this power supply is from 90 vac to 260 vac. the pfc stage board also provides the 3.3 volts to powering-up the dspic dsc, the isolation circuitry, the communication ports, the starter kit programmer, etc. it also gen- erates the 3.3 volts for powering the analog circuits and the analog reference for the analog-to-digital converter.
dspicdem? mchv development system user?s guide ds70605a-page 32 ? 2009 microchip technology inc. the 3.3 volts rail is created using a step-down regulator which is attached to the 15 volts regulator. the maximum output current is 0.650 a, thus the resultant maximum power is 2.145 w. the 3.3 volts rail required for the analog circuits such as the current feedback and the analog-to-digital converter is generated by a decoupling circuitry attached to the 3.3 volts regulator. 4.1.5 fault circuitry given the development nature of the system, robust independent fault protection is provided on the pfc stage board. two different fault categories are used to indicate a fault to the dspic ? dsc. dc bus overcurrent, this fault signal is generated when the maximum current limit of 15a is reached. the comparison of the threshold value and the actual current is done by comparator u8. the threshold limit is set by r56 and r57. r69 is a shunt jumper resistor that can disconnect the overcurrent fault to the dspic dsc. dc bus overvoltage, this fault signal is generated when the maximum voltage limit on the dc bus rails is reached. the threshold value is set to 432 v. the comparison of the threshold value and the actual dc bus voltage is done by comparator u7. the thresh- old limit is set by r60, r61 and r62. r66 is a shun jumper resistor that can disconnect the overvoltage fault to the dspic dsc. 4.1.6 board connectors the pfc stage board has four tab fast-on connectors, one ac inlet and one 14-pin keyed connector for attaching a flat cable. for the ac mains supply input, standard double-insulated, 3-core flex cable should be used with a minimum current rating of 10a (1 mm 2 18 awg). a computer power cable can be used. the recommended cable size is 1.0 to 1.5 mm 2 (18-16 awg) and it should have a 600v rating. this cable should also be double insulated or have a protective ground screen. the tab fast-on connectors ac_n and ac_l provides the connections to the bridge rectifier br1. the recommended cable size is 16-18 awg or 1.0 to 1.5mm 2 . it is also recommended that cables used for the power connections should be terminated with blue or red crimp terminals. if crimp terminals are not used, care should be taken to ensure that stray strands of wire do not short to adjacent terminals or the enclosure. if possible, all wires should be stripped and tinned with solder before connecting to the dspicdem mchv development board terminals. note: both comparators are open-drained and need an external pull-up resistor. both circuits share this pull-up resistor creating an or condition at the output. note 1: the system is designed for installation category ii. therefore, the incoming mains cable should be wired into a standard non-locking 2-pin in addition with an earth ground type plug. 2: the unit is designed to be connected to the ac mains supply via a standard non-locking plug. as the unit has no mains switch, this plug constitutes the means of disconnection from the supply. therefore, the user must have unobstructed access to this plug during operation.
