Boost PFC Converter with One Cycle Control

One cycle control is a novel nonlinear control method for power converters. A one cycle controlled switch has the ability to reject the input voltage perturbation or the load step and to realize control objective only one switching cycle.In this paper one cycle control is introduced to Boost converter to achieve power factor correction (PFC).On the basis of brief introduction of one cycle control,the control objective with one cycle control was summarized.The control aim,its implementation and experimental results are given in detail. Experimental results indicate that one cycle control method can be applied to Boost converter to realize power factor correction.
