Buck-Boost功率因数校正(PFC)转换器具有很宽的直流输出电压范围。本文提出了V接逆变器在降低逆变器成本方面的应用。首先讨论了串联平滑电容的电压平衡问题。其次，讨论了减小输入电流纹波的双变流器结构。最后，提出了一种系统工作在不连续电流模式(DCM)时Buck-Boost PFC变流器的软开关方法。
The buck-boost power factor corrected (PFC) converter has wide range of the DC output voltage. In this paper, the application for the V-connected inverter to reduce the cost of the inverter is proposed. First the balance of series connected smoothing capacitor voltage is discussed. Next, double converter configuration to reduce the input current ripple is discussed. Finally, a soft-switching method of the buck-boost PFC converters when the system operates in the discontinuous current mode (DCM) is proposed.
