Abstract

The design of high power AC-DC converters with higher efficiency is a challenging task, specially with the consideration of the long term short circuit withstand capabilities. This kind of power supplies are commonly used in Arc welding power supplies and other variable load supplies. This paper discusses about the design and implementation of a 4kW AC-DC converter with output voltage stability, current limiting and the long term short circuit withstand capability. Also a special type of snubber circuit is discussed.
