6 / 8 page MITSUBISHI <INTELLIGENT POWER MODULES> PM50B4LB060 FLAT-BASE TYPE INSULATED PACKAGE Oct. 2005 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. •Fast switching opto-couplers: tPLH, tPHL ≤ 0.8µs, Use High CMR type. •Slow switching opto-coupler: CTR > 100% •Use 3 isolated control power supplies (VD). Also, care should be taken to minimize the instantaneous voltage charge of the power supply. •Make inductance of DC bus line as small as possible, and minimize surge voltage using snubber capacitor between P and N terminal.
