Rolling stock use many different types of power electronic equipment such as main motor drives, auxiliary power supply units, air conditioning equipment and door operating devices. This page provides information on Fuji Electric power semiconductor products that are ideal for the power electronics of railroad cars.
Main Converter Circuit Example
These are examples of the main motor drive circuit configuration. The voltage may be either AC or DC. For AC, after passing through the transformer, the power is converted to DC by the PWM converter and then the main motor is driven by the VVVF inverter.
