Abstract

The phase-shifted full bridge (PSFB) ZVS-PWM converter is widely adopted in medium to high power applications. But the conventional PSFB has many limitations and many improved topologies have been proposed to improve the performance of the PSFB ZVS converter. This paper presents a detailed review for these techniques. The merits and limitations of these techniques are analyzed and their key features and characteristics are compared. Based on the review and comparison, an improved PSFB ZVS converter is proposed. A guidance of selection optimized topology for practical application is also discussed in this paper. Related Simulation results and experimental results are presented.
