An inverter module for an electric railcar includes an inverter composed of three 2 in 1 IGBTs, a breaker composed of semiconductor line breaker, and a dry filter capacitor, wherein one inverter corresponds to a single motor. The inverter is a snubberless inverter omitting a snubber capacitor, and a main circuit connecting the output of the inverter to the motor is a coaxial cable. The main circuit and the interior of the inverter is connected via a connector instead of a conventional terminal block.
