For many years the Japanese railway industry has been leading the world in the field of power electronics applications. Approximately 10 years ago, it was the first introduce in electric railcar driving systems the gate turn-off thyristor (GTO), which has a self quenching function for use as a on-board inverter. Now the GTO inverter is widely used in the industry. At the same time, insulated gate bipolar transistors (IGBT) has come to be applied to general-purpose inverters; however, it is too small in capacity to apply to high voltage, large current devices such as on-board inverters because of its low withstand voltage (1400 V or less). To solve this problem, Hitachi, Ltd. has developed an IGBT with a 2000 V withstand voltage, currently the highest in the world, and has succeeded in commercializing a version which is being used in electric railcar driving systems. In consideration of modern demands on environmental awareness (low noise and pollutionfree) and business efficiency (energy saving, labor saving, and higher performance) this IGBT inverter system was commercialized under the concept of environmental-friendliness. It is an ideal electric railcar driving system for the next generation.
