Boost PFC Converter with One Cycle Control

单周期控制是一种用于功率变换器的新型非线性控制策略,当输入电压发生扰动或负载快速变化情况时,仅在一个周期内就可实现控制目标。本文将单周期控制引入Boost变换器,实现了功率因数校正。在阐述单周期控制原理的基础上,总结了单周期控制实现的控制目标。详细给出了单周期控制Boost变换器实现功率因数校正的控制目标和实现方式。实验结果表明,单周期控制适用于Boost变换器实现功率因数校正。

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.
