一种在宽输入电压范围内具有高效率的灵活模式无桥Boost PFC整流器

For the conventional PFC rectifiers, the high efficiency cannot be achieved over a wide input range, and the efficiency will be greatly decreased at low-input voltages. In order to overcome the efficiency bottleneck under low-line input, a flexible mode bridgeless boost power factor correction (PFC) rectifier is proposed in this paper. According to the input voltage, the proposed rectifier can be ...
