Frequency-based current-sharing techniques for paralleled powerconverters

摘要

A new current-sharing technique for paralleled power converters,nwhich is based on frequency encoding of the current-sharing information,nis introduced. The approach has significant advantages over existingnmethods, including the ability to transformer isolate or eliminatencurrent-sharing control connections. Operation of the current-sharingntechnique is analyzed, and the design and experimental evaluation of anthree-cell prototype system are presented
