Study on a Novel High-Efficiency Bridgeless PFC Converter

Autor: Cao Taiqiang, Chen Zhangyong, Wang Jun, Sun Zhang, Luo Qian, Zhang Fei

Publikováno v: Journal of Applied Mathematics, Vol 2014 (2014)

In order to implement a high-efficiency bridgeless power factor correction converter, a new topology and operation principles of continuous conduction mode (CCM) and DC steady-state character of the converter are analyzed, which show that the convert
