Analysis, simulation and design of the Mapham converter

Abstract

In the mid to late sixties, Dr. Neville Mapham worked extensively as an application engineer in the Semiconductor Products Department of the General Electric Company, where he specialized in inverters and the high frequency operation of silicon controlled rectifiers. His success in the power electronics field produced three equivalent parallel output resonant converter configurations, the center tapped supply, the bridge, and the center tapped load. To further expand on Dr. Mapham's work, this thesis simulates, analyzes, and designs the center tapped supply and bridge topologies. Simulation of both configurations is conducted utilizing PSpice software. In addition, the center tapped supply converter is constructed and studied in the Power Systems Laboratory. For design purposes, a specific listing of hardware components is given. Series connection through a transformer of the Mapham bridge is investigated and implementation issues are addressed.
