Abstract
This paper presents a sliding mode control for a multiphase synchronous buck converter with chattering reduction, which is capable to operate with fixed switching frequency at steady state. The system works with a Master-Slave configuration. The chattering reduction is achieved using interleaved control action, while the switching frequency is regulated using a variable hysteresis band comparator for the Master phase. Experimental results show that interleaving operation, robust output regulatio...
