Abstract

Steady-state analysis of a ZVS-PWM controlled series resonant converter with active-clamp technique is presented. In this paper, the normal load characteristics and abnormal voltage increase in the case of light load are analyzed. As a result, it is clarified that the stray capacitance of the transformer is a cause of the abnormal voltage increase. Then, it is confirmed that the abnormal voltage increase is suppressed by decreasing the duty ratio. ZVS condition is analyzed and confirmed experimentally. The ZVS is realized in a wide load range. The maximum efficiency of 89% is obtained for the output of 10 V and 2 A.
