Modified 멀티레벨 컨버터 기반 펄스모드 동작 직류전원장치 = A Pulsed Mode Operating DC Power Supply Based on Modified Multilevel Converter

다국어 초록 (Multilingual Abstract)

This paper describes a high voltage high power DC power supply which has the ability of pulsed mode operation. The power supply is constructed with several series connected power converters based on modified multilevel converters. The modified multilevel converters are suitable for the protection of frequent output short-circuit The output dc power of the proposed converter can be disconnected from the load within several hundred microseconds at the instant of short-circuit fault The using time of the dc load voltage is as small as several hundred microseconds, and there is no overshoot of the dc voltage because the dc output capacitors keep undischarged state Analysis, simulations, and experiments are carried out to investigate the operation and usefulness of the proposed scheme
