Document Type and Number:
WIPO Patent Application WO/2017/203624
Kind Code:
The purpose of the present invention is to achieve size reduction and simplification of the circuit configuration of an intelligent power module (IPM) through phase synchronization of the IPM. The IPM pertaining to the present invention comprises: a multi-phase-arm DC-DC converter 11 in which multiple phase-arms are parallelly connected on the secondary side thereof; a secondary-side wire voltage detection circuit 12 for detecting secondary-side wire voltages of each of the phase arms of the DC-DC converter 11; and a synchronization signal generation circuit 13 for generating a synchronization signal for each of the phase-arms on the basis of the behavior of the secondary-side wire voltage.
