NOTES FOR STABLE AND SAFE OPERATION ;

• Design the PCB pattern to minimize wiring length between opto-coupler and IPM’s input terminal, and also to minimize the

stray capacity between the input and output wirings of opto-coupler.

• Connect low impedance capacitor between the Vcc and GND terminal of each fast switching opto-coupler.

• Slow switching opto-coupler: CTR > 100%

power supply.

• Make inductance of DC bus line as small as possible, and minimize surge voltage using snubber capacitor between C1 and

E2 terminal.
