摘要：

This paper presents an optimized design procedure for a dc-dc buck-boost converter associated with a dissipative snubber. Initially, the static gain of the converter is determined from the charging and discharging times of the inductor in an approach that is valid for any conduction mode and does not depend on the load condition. The influence of the snubber circuit is also analyzed considering tradeoffs between the maximum voltage stress across the switch and related losses. Experimental results are also presented in order to validate the theoretical assumptions.
