Abstract


Integrated power electronic devices has become an important trend in power electronics technology of the future development of extensive attention by international power electronics sector . This paper introduces the concept of integrated power electronics , and a review of the integrated development of the power electronics course , summarizes the methods and key technologies of power electronics integration . In particular , provides an overview of the integration of the single- phase Boost power factor correction circuit . In this paper, the parameters of the work in the high-frequency composite active clamp Boost PFC converter design . First analyzes the various working stages of the converter , in particular analysis of the voltage stress of the soft switching conditions of the circuit and the switching device , by these theories , analysis, design, the resonance parameters of the main circuit . Then , the mating of the two drive control circuit are introduced, and the design of the control loop parameters . In this paper, the actual unit of the composite active clamp Boost PFC converter main circuit parasitic parameters of calculation and measurement parasitic resistance and parasitic inductance and parasitic capacitance values ??. Circuit modeling , using Orcad software the ideal circuit joined the parasitic circuit simulation , parasitic parameters of the circuit run by the comparison of the two sets of waveform can be seen . This paper described the selection of power devices , and the design parameters of the drive circuit . For a complete circuit of the system , the protection circuit is an essential part of the article on the principle of circuit protection make the description . Meanwhile, the characteristics of Boost circuit design soft-start circuit . The last circuit experimental results are given , and the experimental results and the theoretical analysis and simulation results are basically the same .
