Implementation of a simple rotating master control scheme for parallel converters

Rotating master-slave current programming method (RMSCPM) is known in theory for long time. Advantage of the rotating master method is a better system reliability, comparing to the dedicated master method. However, practical implementation of this method can be very complicated due to a large number of signals to be swapped during control rotation. This paper presents a practical scheme for extremely simple implementation of rotating master-slave current programming method (RMSCPM).
