Abstract

This paper proposes a new circuit topology for a high efficiency isolated DC/DC converter using series compensation. The proposed converter consists of a high efficiency resonance half-bridge converter and a series converter. The series converter regulates the output voltage the provides only the differential voltage between the input voltage and output voltage. Therefore, the circuit achieves high efficiency when the input voltage is almost equal to the output voltage, because then only the resonance converter will operate.
In this paper, the approach employed to achieve a high efficiency by using the proposed series compensation method is introduced. In addition, the fundamental operation and the method of designing the proposed circuit are described. The suitability of the proposed circuit was confirmed by performing an experiment and loss analysis, maximum efficiency achieved was 96.2%.
