11 applications information eliminating negative igbt gate drive to keep the igbt fi rmly off , the acpl-p314/w314 has a very low maximum v ol specifi cation of 1.0 v. minimizing r g and the lead inductance from the acpl-p314/w314 to the igbt gate and emitter (possibly by mounting the acpl-p314/w314 on a small pc board directly above the igbt) can eliminate the need for negative igbt gate drive in many applications as shown in figure 19. care should be taken with such a pc board design to avoid routing the igbt collector or emitter traces close to the acpl- p314/w314 input as this can result in unwanted coupling of transient signals into the input of acpl-p314/w314 and degrade performance. (if the igbt drain must be routed near the acpl-p314/w314 input, then the led should be reverse biased when in the off state, to prevent the transient signals coupled from the igbt drain from turning on the acpl-p314/w314. selecting the gate resistor (rg) step 1: calculate r g minimum from the i ol peak specifi - cation. the igbt and r g in figure 19 can be analyzed as a simple rc circuit with a voltage supplied by the acpl- p314/w314. r g 270 v cc = 24v + - 6 1 5 2 4 3 0.1 f +5 v control input 74xxx open collector + hvd -hvdc 3-pha se ac q1 q2 acpl-p314/w314 + - 1 figure 19. recommended led drive and application circuit for acpl-p314/w314 figure 20. energy dissipated in the acpl-p314/w314 and for each igbt switching cycle. step 2: check the acpl-p314/w314 power dissipation and increase r g if necessary. the acpl-p314/w314 total power dissipation (p t ) is equal to the sum of the emitter power (p e ) and the output power (p o ). the v ol value of 5 v in the previous equation is the v ol at the peak current of 0.6a. (see figure 6). where k icc q g f is the increase in i cc due to switching and k icc is a constant of 0.001 ma/(nc*khz). for the circuit in figure 19 with i f (worst case) = 10 ma, r g = 32 ? , max duty cycle = 80%, q g = 100 nc, f = 20 khz and t amax = 85c: the value of 3 ma for i cc in the previous equation is the max. i cc over entire operating temperature range. since p o for this case is less than p o(max) , r g = 32 ? is alright for the power dissipation. 32 0.6 24 ? 5 i v v r olpeak ol cc g = = ? 3 (r ) u f )(r) f q ; e v f q k q ; e v i p p dutycycle v p p p g g sw cc g icc ccbias g g sw cc cc o(switching) o(bias) o f f e o e t u + u u u + = (i + u = + = p u u = i + = p @85 c) 0.4 j u 20 khz = 128 m w 250 m w ( p p p o(max) o e = (3 m a + (0.001 m a/nc u khz) u 20 khz u 100 nc) u 24v + = 10 m a u 1.8v u 0.8 = 14 m w esw ? energy per switching cycle ? j 0 0 rg ? gate resistance ? 100 1.5 20 4.0 40 1.0 60 80 3.5 qg = 50 nc qg = 100 nc qg = 200 nc qg = 400 nc 3.0 2.0 0.5 2.5
12 led drive circuit considerations for ultra high cmr per- formance without a detector shield, the dominant cause of opto- coupler cmr failure is capacitive coupling from the input side of the optocoupler, through the package, to the detector ic as shown in figure 21. the acpl-p314/w314 improves cmr performance by using a detector ic with an optically transparent faraday shield, which diverts the capacitively coupled current away from the sensitive ic circuitry. however, this shield does not eliminate the ca- pacitive coupling between the led and optocoupler pins 5-8 as shown in figure 22. this capacitive coupling causes perturbations in the led current during common mode transients and becomes the major source of cmr failures for a shielded optocoupler. the main design objective of a high cmr led drive circuit becomes keeping the led in the proper state (on or off ) during common mode tran- sients. for example, the recommended application circuit (figure 19), can achieve 10 kv/ ? s cmr while minimizing component complexity. techniques to keep the led in the proper state are discussed in the next two sections. cmr with the led off (cmrl) a high cmr led drive circuit must keep the led off (v f ? v f(off) ) during common mode transients. for example, during a -dv cm /dt transient in figure 23, the current fl owing through c ledp also fl ows through the r sat and v sat of the logic gate. as long as the low state voltage developed across the logic gate is less than v f(off) the led will remain off and no common mode failure will occur. figure 21. optocoupler input to output capacitance model for unshielded optocouplers. figure 22. optocoupler input to output capacitance model for shielded optocouplers. c ledp c ledn 6 1 5 2 4 3 c ledp c ledn 6 1 5 2 4 3 c ledp c ledn 6 1 5 2 4 3 shield c led01 c led02 c ledp c ledn 6 1 5 2 4 3 shield c led01 c led02 c ledp c ledn 6 1 5 2 4 3 shield i ledp r g v cc = 18v + - 0.1 f + - the arrows indicate the direction of current flow during - d v cm /dt +5 v v sat + - v cm i + - + - v sat + - v sat + - ? ? figure 23. equivalent circuit for figure 17 during common mode transient. cmr with the led on (cmr h ) a high cmr led drive circuit must keep the led on during common mode transients. this is achieved by overdriving the led current beyond the input threshold so that it is not pulled below the threshold during a transient. a minimum led current of 8 ma provides adequate margin over the maximum i flh of 5 ma to achieve 10 kv/s cmr. the open collector drive circuit, shown in figure 24, can not keep the led off during a +dv cm /dt transient, since all the current fl owing through cledn must be supplied by the led, and it is not recommended for applications requiring ultra high cmr1 performance. the alternative drive circuit which like the recommended application circuit (figure 19), does achieve ultra high cmr perfor- mance by shunting the led in the off state. figure 24. not recommended open collector drive circuit. c ledp c ledn 6 1 5 2 4 3 shield i ledn +5 v q1 c ledp c ledn 6 1 5 2 4 3 shield i ledn +5 v q1 q1
