To obtain high performance control of a DC-DC converter, designing and simulation of PI and PID based controller for DC-DC buck converter and DC-DC Synchronous Buck Converter is done in the paper. Parameters of both converters at regulated and unregulated DC supply are analyzed in this paper.

DC-DC Buck Converter and DC-DC Synchronous Buck Converter is also compared in this paper and results are verified. Soft switching techniques in Synchronous Buck Converter are used to reduce the switching losses and remove the power losses. Simulation works are done in MATLAB environment.
