Title: MAIN CONVERSION CIRCUIT, POWER CONVERSION DEVICE, AND MOVING BODY
Abstract:
A main conversion device has a plurality of semiconductor devices (1) connected in parallel with each other. A gate driver (13) supplies a gate voltage to the gates of the semiconductor devices (1). Gate interconnections (14, 16) are each sequentially connected to the gates of the semiconductor devices (1) from the gate driver (13). The energizing ability of each of the semiconductor devices (1) indicates how easily collector current flows in response to the supplied gate voltage. The semiconductor devices (1) are connected such that a semiconductor device (1) having a lower energizing ability is connected closer to the gate driver (13).
