Proposed method significantly suppresses oscillations in phase-shifted full-bridge dc-dc converters, indicating improved dynamic performance.
Phase‐shifted full‐bridge (PSFB) converters have become a mainstream isolated DC/DC topology due to their simple control, reliable structure, low switching stress, and excellent dynamic characteristics. However, in practical applications, PSFB converters face the challenge of parasitic oscillations. This paper analyzes the mechanism of rectifier diode oscillations in detail and proposes an effective suppression method. The proposed approach demonstrates strong oscillation suppression, simplicity in principle, and minimal impact on converter volume. Experimental results validate the effectiveness of the method.
