Abstract :
Boost phase-shifted (PS) full-bridge (FB) converter is a typical converter in high voltage application. Due to the requirement of high voltage insulator, its transformer is often designed with more leakage inductor and inter-layer capacitor. Considering leakage inductor and inter-layer capacitor´s effect, accurate model of Boost PS FB converter is established. The difference between this model and the conventional model is analyzed. Based on this model, the closed-loop small signal model with average current-mode control is also given. The experimental results on a 530 V/15 kV, 5 kW prototype proved the theoretical analysis.
