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.
