We have completed the systematization of power transistor devices of 500 V and 1000 V in breakdown voltage, and max. 200 A in current capacity. Since the electrical characteristics and package structure of these power transistors are designed to meet the circuit designers' requirement sufficiently, they can be applied to large capacity power converters, with compact structure and high performance provided. This paper reports the features of the new power transistors, the technique of application to power converters, and examples of the transistorized power converters.
