基于自适应查找表的CRM Boost PFC变换器变导通时间控制

This paper proposes an adaptive look-up-table (LUT)-based variable on-time (VOT) control for CRM boost PFC converters, which combines advantages of conventional LUT method and real-time calculation method. By the numerical fitting method, the approximate functional form of the on-time is derived, which is related to both the input voltage and load. The mapping relationships of VOT tables under dif...
