Experimental Study on Improved Phase-Shift Control Soft-Switching Converter

Abstract:

A novel phase-shifted Soft-switching converter is presented in this thesis，which is based on the Tou structural, groundwork of summarization of the development of lower Electronics in recent years and lucubration in theoretical basis of modern high frequency soft switching power convert technique and analysis of operation principle, characteristic of the circuit and inherent drawbacks of traditional phase-shifted Soft-switching converter. Explicit description of main circuit topology, operation principle, characteristic of the circuit of the novel phase-shifted Soft-switching converter as well as the simulation analysis with the PSPICE software is proposed. The main works that I did: The design involves calculation of transformer, inductor and capacitance in main circuit, parameter selection of each element and realization of control circuit. Electric circuit Tou structural is verified by emulation experiment. The electric circuit reduces availably switch exhaust of traditional soft switch transformation electric circuit. The experiment proved to the possibility of the reformed prefect. The experiment has important reference value to improved soft switch transformation.
