要約(英語): To switch high-voltage and high-current pulses by using MOS (Metal Oxide Semiconductor) transistors, it is necessary to distribute evenly the voltage and current to each element connected in series and parallel. In parallel connection, the current flowing in each element is different depending on the series resistance and wiring inductance. We verified improvements on pulsed current sharing in parallel transistors which were arranged in line on a printed circuit board. Although Gate and Drain wirings are different in length, pulsed current was evenly distributed by using transmission line transformers. Dissipation in transistors were equalized and four transistors were driven simultaneously near the rated current.
