Abstract

Provided are a sub inverter of a full-bridge constituted by two arms: an arm and an arm, each of which is mounted on a different module, a main controller to drive and control the sub inverter by switching an operation mode between a first mode in which a first arm performs a low-frequency switching operation and a second arm performs a high-frequency switching operation, and a second mode in which the second arm performs a low-frequency switching operation and the first arm performs a high-frequency switching operation, and an operation ratio setting circuitry to set an operation ratio on the basis of a bias of a temperature rise between the modules.
