摘要
Abstract
Aiming at the problem of poor line characteristics of the critical Boost-PFC circuit with traditional constant on-time control for the obvious crossover distortion,three simplified variable on-time(VOT)control strategies were proposed to improve the line characteristics of the circuit.The three kinds of VOT control strategies were compared and analyzed in detail.Finally,the computer simulation and 200 W prototype experiment were carried out.The computer simulation and experimental results show that the proposed three VOT control strategies can effectively improve the grid-side characteristics of the circuit and the efficiency of the circuit.关键词
