6 / 8 page MITSUBISHI <INTELLIGENT POWER MODULES> PM75CLB120 FLAT-BASE TYPE INSULATED PACKAGE May 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 4 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. •Use line noise filter capacitor (ex. 4.7nF) between each input AC line and ground to reject common-mode noise from AC line and improve noise immunity of the system. : Interface which is the same as the U-phase Fig. 8 Application Example Circuit OUT Si OT OT OT OT OT OT GND GND In Vcc U V W NC N P M ¡ IF + – OUT Si GND GND In Vcc OUT Si GND GND In Vcc OUT Si GND GND In Fo Fo Fo Fo Vcc OUT Si GND GND In Fo Vcc OUT Si GND GND In Fo Vcc VWP1 WP VWPC UN VN VN1 WN VNC 1.5k 1.5k 1.5k 1.5k Fo VVP1 VP VVPC ≥0.1 µ 1k ≥0.1 µ ≥0.1 µ 20k 20k 20k ≥10 µ ≥10 µ ≥10 µ 20k ≥10 µ ≥0.1 µ VFo WFo UFo VUP1 UP VUPC NC ¡ ¡ IF IF IF 5V ¡ VD VD VD VD |
