Abstract

DC-DC converters are needed to supply power with high efficiency in various applications in industry. However, the conventional DC-DC converters cannot achieve higher efficiency mostly owing to the switching and conduction losses. On the basis of existing topologies, in this study a novel ZVT auxiliary circuit with dual resonant tank for the DC-DC converters with synchronous rectification (SR) is proposed. The proposed ZVT auxiliary circuit aims at reducing losses of conventional DC-DC converters by using zero-voltage-switching, zero-current-switching and SR with reduced reverse recovery time of junction diodes. To verify the proposed circuit, a Buck converter integrated with the proposed dual resonant tank is implemented in this study. The simulated and experimental results obtained have demonstrated that the proposed dual resonant tank can be practically implemented in conventional DC-DC converters to provide better performance as compared with existing topologies
