Abstract

The analysis and design of an improved single-ended switched-mode rectifier (SMR) converter topology is presented. The novel feature of this topology is a nondissipative LC-type subcircuit which provides transformer flux balancing and improves converter efficiency. This is achieved by minimizing switching losses and by returning the energy stored in the transformer leakage and circuit stray inductances to the source and the load. Theoretical predictions and SMR converter design procedures are verified experimentally on a 1 kW 20 kHz prototype circuit
