High Efficiency PFC Frontend for Class-D Amplifiers

Li, Qingnan

Technical University of Denmark — 2012

This thesis investigates the design of high eciency Power Factor Correction (PFC) converter for Class-D amplier at universal line and 3.5kW power range. The work starts with an overview on dierent high eciency Bridgeless PFC topologies and investigates their applicability with respect to the given

Research on High Efficient Single-Phase Multi-Stage Interleaved Bridgeless PFC Frontend for Class-D Amplifiers

Li, Qingnan; Thomsen, Ole Cornelius; Andersen, Michael A. E.

2012 Ieee 7th International Power Electronics and Motion Control Conference — 2012, Volume 2, pp. 1054-1059

In this paper, a 3.5kW single-phase high efficient interleaved Bridgeless PFC (IBPFC) is proposed for class-D amplifiers. This topology achieves a relatively higher efficiency in a wide output power range, which helps to reduce the energy consuming of the whole system. In addition, a detailed
