Abstract

A lossless turn-on snubber was studied analytically, by simulation and experimentally. Limits were found for the proper operation of the snubber and are expressed as permissible duty cycle as a function of input current. It was found that a modified version of the snubber, which includes a tapped main inductor, improves the performance by allowing a wider operational range. The experimental results confirm the theoretical analysis. A reduction of power losses of about 19 W was observed when the snubber was implemented in a 1 kW boost power converter
