Low Cost μC Based Dc-Dc Boost Converter with Passive Snubber Circuit

this brief introduces a method of improving the power conversion efficiency of a dc-dc boost converter with passive snubber circuit. This method uses a passive snubber circuit which consists of two inductors, a capacitor, and a diode, to reduce switching loss. The use of passive soft switching methods has been emphasized as better alternative to active methods mainly because they do not require extra switches or additional control circuitry. They are less expensive, have higher reliability, and have been reported to achieve higher performance.In this paper, a new highefficiency dc–dc boost converter with a passive snubber circuit is proposed. Passive soft-switching methods have been used to reduce these switching losses.
