Abstract
In this paper, a new dc/dc converter with high efficiency using soft switching by partial resonant circuit is studied. The proposed converter circuit is used to replace the conventional snubber circuit of Buck-Boost converter with a pair of diodes, lossless capacitor and a step up inductor. In addition the output voltage is regulated by varying the switching frequency with varying load making it a frequency dependent converter rather than a load dependent converter. In comparison to the conventional Buck Boost converter with some simulation results confirm the validity of analytical results of the proposed converter.
