Abstract :
A novel zero-voltage-switching (ZVS) scheme is described for a cycloconverter-type high-frequency inverter applicable for renewable/alternative energy sources. the proposed scheme achieves primary-side-converter assisted switching of the ac/ac converter switches under ZVS condition. The scheme is applicable for both unity and non-unity-power-factor loads. It also mitigates diode reverse-recovery problem, evident in competing conventional schemes, thereby enabling high-frequency switching with minimal compromise in efficiency. The modes of operation of the ac/ac converter are explained to outline the behavioral response. Results on the efficacy of the ZVS-based inverter and its performance show satisfactory performances.
