6 / 8 page MITSUBISHI <INTELLIGENT POWER MODULES> PM200CLA120 FLAT-BASE TYPE INSULATED PACKAGE Jul. 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 6 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 GND GND In Vcc U N V N P P W N P M ¡ IF + – OUT Si GND GND In Vcc OUT Si GND GND In Vcc Fo Fo Fo VVP1 VP VVPC 1.5k 1.5k 1.5k VUN1 UN VUNC 20k ≥10 µ ≥0.1 µ UNFO VPFO UPFO VUP1 UP VUPC VD OT OUT Si GND GND In Vcc Fo VVN1 VN VVNC 1.5k VNFO VD OT OUT Si GND GND In Vcc Fo VWP1 WP VWPC 1.5k WPFO VD OT OUT Si GND GND In Vcc Fo VWN1 WN VWNC 1.5k WNFO VD VD VD |
