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

This paper describes a new notches generator for the test of custom power devices such as UPS, DVR, Active Power Filter, etc The magnitude, width, polarity, and position of the notches generated by the proposed scheme can be varied with simple control. The scheme has good features of simple structure, high reliability, and the capability of arbitrary several notches generation. The Circuit operation is described and the usefulness of the scheme is verified through simulations
