Abstract :
In this paper, a small signal model of a novel ZVZCS FB-PWM DC/DC converter is built and analyzed. A double closed loop controller is employed: the inner loop is a PI controller and the outer loop is a fuzzy logic with integrator controller. The novel control strategy improves the performance of the converter greatly, such as stability, control precision and dynamic response. The dramatic feature of topology and the superiority of control strategy are proved by experiment results on a 3 kW prototype
