High Efficiency DC-DC Buck Converter with a Passive Snubber Circuit
This paper proposes a method to reduce turn-on and turn-off switching losses of a direct-current-direct-current (DC-DC) buck converter. A passive snubber circuit, which includes one inductor, one resistor, two diodes and three capacitors, was used to increase the power conversion efficiency. The maximum efficiency of the proposed converter for an output power of 120 W was measured as 96.33%, which is 0.62 ~1.46% higher than the conventional buck converter and other buck converters with the passive snubber circuits. The proposed snubber circuit operates stably under sudden changes in the load.
