The objective of this M.S. Thesis was to design, simulate, construct and test a pulse-width-modulated Buck DC-DC Converter and its compensated feedback system. Equations for the design and component selection of a buck converter have been obtained for operating the buck converter in the continuous conduction mode (CCM). A hardware version of the converter design has been implemented to demonstrate the functionality of the designed converter. Also, a digital buck converter control system has been designed and simulated. This digital buck converter led to the development of a proposed control scheme for Switched Mode Power Supplies (SMPS).

A novel hybrid feedback control scheme has been proposed, analyzed and simulated. This proposed novel control system implements a proposed novel device that accepts commands from an intelligent source, such as a processor, while allowing the SMPS to apply power to the system under analog control. Once the processor is functioning, it can adjust and tweak characteristics of the power supply to obtain the best power output for the operating environment.
