An Integrated High-Power-Factor Converter With ZVS Transition PROJECT TITLE :An Integrated High-Power-Factor Converter With ZVS TransitionABSTRACT:This paper proposes a single-section high-power-factor ac/dc converter with soft-switching characteristic. The circuit topology is derived by integrating a lift converter and a buck converter. The boost converter performs the operate of power-issue correction to get high power factor and low current harmonics at the input line. The buck converter additional regulates the dc-link voltage to provide a stable dc output voltage. While not using any active-clamp circuit or snubber circuit, the active switches of the proposed converter will achieve zero-voltage switching-on transition along with high power issue that satisfies the IEC 61000-3-2 standards over a large load vary from 30% to one hundred% rated power. The steady-state analysis is developed and a design example is provided. A prototype circuit of sixty W was engineered and tested. Experimental results verify the feasibility of the proposed circuit with satisfactory performance. Did you like this research project? To get this research project Guidelines, Training and Code...
