Abstract:
In the research, a full-bridge converter with the leakage inductance absorber is developed. The proposed converter can reduce the high voltage stress caused by leakage inductance, simultaneously achieve the functions of surge suppression. The absorber can be regarded as a passive snubber to reduce the ringing frequency. It includes four diodes and a single recovery capacitor, which has advantages of the simple structure and bipolar energy absorption. From the measured waveforms, the amplitude of the voltage spike across the active switches are significantly suppressed, and the ringing is also effectively alleviated. It proves that the proposed leakage inductance absorber can be applied to the full-bridge converter.
