摘要
Abstract
Power factor correction(PFC)is an important issue in switching power supply design. PFC is widely used due to its simple peripheral circuits and high-power factor,but design of the PFC external parameters is difficult. To solve this prob-lem,a method to determine the external parameters is proposed. The internal structure of the control device is analyzed theoreti-cally,mathematical model is established and Matlab simulation analysis is performed,so as to fully grasp the influence of exter-nal parameters on the control performance of the system,and avoid too many blind spots in the debugging process. If the parame-ters determined with this method is apply to the actual circuit,a high-power factor switch power supply with high performance can be designed by means of a simple debugging.关键词
