Abstract
Since the switching device of current-fed bridge-type topology suffers from him-off voltage spikes associated with larger energy than that of voltage-fed topology, a high-efficiency non-dissipative snubber is considered essential. However, the complicated operation and the capricious performance according to various conditions make the design of the non-dissipative difficult. In this paper, the non-dissipative snubber employed in the current-fed half-bridge converter operating at a duty ratio above 0.5 is completely analyzed and the design considerations are discussed. Some design examples and the experimental results are provided to confirm the analysis and design presented in this paper.
