Abstract :
Advanced application of power-MOSFET to a large capacity novel converter system is studied. Parallel operation of many power-MOSFET elements is investigated in room and liquid nitrogen temperatures. The total on-state resistance shows lowered value in parallel connected and cooled down conditions, and the reduced resistance is effective for operational loss reduction of the converter circuit. The bi-directional switching unit with four power-MOSFET elements is proposed, which can be applied to the self commutated type AC/DC converter. Another type of AC/DC converter using power-MOSFET consists of a three phase synchronous rectifier circuit, which is suitable to output one directional high DC current
