摘要
Abstract
Aimed at the problem that the traditional control methods are difficult to achieve soft-switching in a wide load range due to the limitation of resonant inductor volume and duty cycle loss in phase-shifted full-bridge converters,a hybrid control method based on peak current and Burst mode is proposed.The output voltage is stabilized to a reference value by adjusting the Burst duty cycle,and the phase shift angle is changed to maintain the minimum primary current so as to realize the lagging bridge arm zero voltage switching.A simulation platform was built for the proposed control method,and a 250 W prototype was developed.The hybrid control of a phase-shifted full-bridge converter was realized through a digital signal processor,and the feasibility of the control method was verified by simulation and experimental results.关键词
