Research on All Operation Modes of Chopper Circuit Topology Incorporating Series Connection of Buck and Boost Choppers

Abstract

In this paper we propose a novel chopper circuit topology incorporating series connection of buck and boost choppers. This circuit topology shows various characteristics according to the combination method of operating modes. In these many combinations, we research all operation modes in which the two MOSFETs are on and off at different time. Experimental results show variety of circuit operations by various combinations of operating mode.
