Design and analysis of zero current switching based DC to DC buck converter

Abstract EN

To make the converter size compact, it is to be operated at higher switching frequencies in order oj Kilo's and Mega hertz's.

The operation oj the converter at these higher switching frequencies carrying the entire load current during turn on and turn oJJ instants oj the switch, increases the saiuitching losses and is subjected to large amounts oj di / dt and ajoltage stresses.

Thus the design and analysis oj a high efficient Zero Current Saiuitching (ZCS) based DC to DC buck converter is presented in this paper.

The converter uses the ZCS technique with the concept oj resonant switch, which is a combination oj semiconductor device and LC network, and makes the Switch to turn on and turn oJJ at zero current instant.

This reduces the switching losses and improves the lije time oj the switch.

The simulation results in MATLAB / SIMULINK shows the performance oj the ZCS based DC to DC Buck converter superior to the normal Buck converter.
