Applying Inductor Current Time-Control to Resonant ZCS Boost Converter for Constant Switching Frequency Operation

This paper proposes a converter topology with zero current switching (ZCS) and constant switching frequency capabilities. The proposed converter has an inductor current time-control switch added to the boost ZCS converter, which is a quasi-resonant converter. The gate drive timing will be described in the paper. Steady state analysis of this converter, showing how the constant switching frequency operation works, will be given, together with design and simulation to confirm the analytical work.
