Design of Full Bridge Buck Converter with a Fly back Snubber for High Power Applications

T Rama Rajeswari;C Subramanian, R Manivannan

Abstract

This article deals with the design of a full bridge buck converter along with fly back snubber for high power applications. A fly back snubber is a combination of a diode, a capacitor and a fly back converter. A fly back snubber circuit is used to clamp the voltage spike originating from the current difference between the leakage inductance and current-fed inductor of the isolation transformer. The fly back snubber reduces the current passing at the current-fed side associated with the active switches. The full bridge buck converter along with a fly back snubber has been simulated using MATLAB software and is checked for feasibility with the simulated results of the conventional circuit without a fly back snubber.
