Abstract :
A new type of resonant DC/DC converter is proposed, analyzed and verified experimentally. The circuit is composed of a class D inverter and a class E synchronous rectifier. We apply the thinned-out method to the class E synchronous rectifier and regulate the output voltage at a fixed operating frequency. We have reduced the output voltage for the thinning-out operation in previous research. In this paper the circuit increases the output voltage by applying the class E synchronous rectifier using the thinned-out method to the class D inverter. The DC output voltage is regulated against load and line variations by varying the ratio of thinning-out at a fixed operating frequency. The circuit could increase the output voltage from 3.4 V to 4.2 V maintaining over 65 percent efficiency
