Abstract For the shortcomings of a traditional push-pull converter, a novel soft switch auxiliary circuit with feedback transformers, which assists the two power devices in push-pull converter to switch softly, is proposed. The operating principle is analyzed and a series of formulas to determine the circuit parameters are derived. When the turns ratio and the magnetizing inductance meet the design conditions, the feedback transformer can avoid entering the magnetic saturation. The soft switching push-pull DC/DC converter has been put into use, verifying the correctness of the circuit and the design method.
