POWER CONVERSION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a power conversion apparatus reduced in size and weight while making a a cooling constitution have a minimum necessary capacity by leveling the sharing of heat loss applied to a plurality of coolers.

SOLUTION: The power conversion apparatus connecting in parallel two groups of inverter circuits converting DC power into AC power by switching operations of a plurality of semiconductor elements is characterized by mounting the semiconductor elements constituting two groups of the inverter circuits in one common cooling unit having a heat receiving/radiating part.
