Mitsubishi Electric Corporation have announced its main circuits featuring traction inverter made with all-silicon carbide (SiC), which have been installed in a 1000 series urban train operated by Odakyu Railway Co., Ltd. in Japan, have been verified too achieve an approximate 40% savings on power consumption. This is compared to the conventional circuitry in another train. The results were taken from a four-month period  from the traction inverter, which is rated for 1,500v DC catenaries.

The verification compared a car retrofitted with an all-SiC traction inverter and another car fitted with a conventional gate turn-off thyristor traction inverter, both of which were put into commercial service. The test measured power consumption and electric power regeneration ration of the two cars’ main circuits, which comprise of traction inverters, high-efficiency main motors and filter reactors.
