| 摘 要： | 提出了复合有源箝位(CAC)功率因数校正变换器电路。谐振电感与主开关串联，由辅助开关和箝位电容组成的支路并联在谐振电感两端。谐振电感可以抑止二极管的反向恢复电流，有效的减少由二极管反向恢复引起的损耗，主开关和辅助开关均可实现ZVS开关，消除了二极管寄生电容和谐振电感引起的寄生振荡。该文分析了复合有源箝位功率因数校正变换器中软开关范围与谐振电感和电容之间的关系，研制了一台1kW复合有源箝位功率因数校正变换器。

| Abstract: | A PFC converter employing compound active clamping ( CAC ) technique is proposed. In CAC PFC converter, the resonant inductor is in series with main switch. An active-clamping branch composed of an auxiliary switch and a clamping capacitor is added in parallel with the resonant inductor. The CAC technique can effectively reduce the loss caused by diode reverse recovery. Both the main switch and the auxiliary switch can achieve Zero-Voltage-Switching (ZVS). The parasitic oscillation caused by the parasitic capacitance of the boost diode is eliminated. The soft-switching region with relation to the resonant inductor and resonant capacitance are investigated. A prototype of 1kW is built to test the proposed topology. |
