In this paper, a soft transition push pull converter is proposed, which achieves lossless switching for the two main and two auxiliary switches without increasing the main device current/voltage rating.Abstract:
A novel soft transition push pull converter is proposed in this paper. The proposed circuit achieves loss-less switching for the two main and two auxiliary switches without increasing the main device current/voltage rating. A tapping in the isolation transformer is added for the purpose of commutation. The proposed circuit is capable of operation at elevated switching frequencies of several hundreds of kHz, in a range of line and load variations. Steady state performance, the operating principle and theoretical analysis is outlined for the proposed pushpull converter. The steady state conversion ratio and the equivalent circuit model is presented. Experimental results are presented which verifies the steady state performance of the converter. The experimental waveforms are in agreement with the theoretical.read more
