6 / 6 page MITSUBISHI <INTELLIGENT POWER MODULES> PM50CSE120 FLAT-BASE TYPE INSULATED PACKAGE Sep. 2001 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. •Quick opto-couplers: TPLH, TPLH ≤ 0.8µs. Use High CMR type. The line between opto-coupler and intelligent module should be shortened as much as possible to minimize the floating capacitance. •Slow switching opto-coupler: recommend to use at CTR = 100 ~ 200%, Input current = 8 ~ 10mA, to work in active. •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.
