Abstract

This paper describes the research trends of the high voltage pulsed power modulator based on semiconductor switch. The research on the solid-state pulsed power modulator technology can be classified into three topics that were performed for introducing the topology of pulsed power modulator to overcome the ratings of semiconductor device, increasing the rated power with long pulse width and low voltage droop, minimizing rising/falling time with short pulse width. This paper provides a brief overview of these three research topics and introduces the developed pulsed power modulator in Korea Electrotechnoloy Institute(KERI).
