in this video number {972H} How does an IPM converts DC voltage into three phases to driver compressor. i explained the theory of operation of an IPM intelligent power module. it receives 6 bit drive signals from microcontroller. these signals are processed through high power IGBTs for low side and high side drive signals.

it is used in LG dc inverter ac outdoor unit board EAX64913701 ebr758794. all current passes through its internal shunt and its hall sensor senses the corresponding magnetic field proportional to the current flow and hall amplifier amplifies that signal for further use in processing
