Abstract Details

2011, Master of Science in Engineering (MSEgr), Wright State University, Electrical Engineering.
The objective of this research is to analyze, design and simulate a two-switch forward pulse-width modulated (PWM) DC-DC converter. The Forward PWM DC-DC converter is originally derived from the buck converter by the addition of a transformer. The transformer is mainly used as a safety feature to electrically isolate input and output stages of the power converter and also to scale the voltage or current. The steady-state analysis is presented for the two-switch PWM DC-DC forward converter in continuous conduction mode (CCM). Based on the analysis, the design equations for two-switch PWM forward DC-DC converter are derived. A design example is given. Furthermore, a detailed procedure to design a high-frequency (HF) two-winding power transformer is presented for CCM. The 60 W/ 20 V two-switch forward converter is designed for universal laptop adapter. Simulation results are provided to validate the theoretical analysis.
