Abstract
This paper presents a novel single-stage asymmetrical half-bridge regulator with input current ripple reduction technique. Most of the researched ripple reduction rectifiers cascade a boost-type converter integrates with the system. It is found that the asymmetrical half-bridge resonant converter, when the duty cycles are greater than 50%, can simplify the front end of the boost-type converter to a novel single-stage converter. In order to reduce the converter size and weight and to achieve better low-ripple input current, integrated magnetic and coupled inductor techniques are used in the proposed regulator. The operation principle and steady state analysis of the proposed regulator are discussed in detail. The prototype is built to demonstrate the system performance and effectiveness. © 2008 IEEE.
