Abstract
This paper deals with the analysis, simulation and implementation of an SMPS based on a two-stage AC-DC converter. The first-stage uses a single-phase uncontrolled bridge rectifier, and the second-stage is based on a DC-DC half-bridge converter. The presented SMPS output-voltage can be controlled in the range of 10-15V to supply a DC-load to supply up to 250W to the load. power rating up to 250W. A detailed mathematical analysis is presented to show converter performance in (CCM). The effect of inserting the flux reset capacitor between the primary of the high frequency converter and the two power transistors center point are taken in to account in this work. The SMPS is modeled in MATLAB Simulink, and the results are cross-checked against the analytical representation as well as the results of a developed microcontroller-based prototype model, resulting in a complete validation.
