Guys,
I need some help in understanding IPM circuits and how they control a DC Inverter Compressor. Im familiar with all the circuits, but cant seem to nail down the sequence of operation once DC Voltage gets to the IPM. and how it affects compressor speed. I would like to be able to troubleshoot the compressor and the IPM circuit to determine which is at fault. I would love to find some books on the subject. Any ideas please.
