摘　　要：传统有桥单相有源功率因数校正器可采用分流电阻压降反映电感电流瞬时值用于电流内环控制,该方法也可直接用于准无桥APFC。但是APFC高频化发展趋势要求使用低感值交流电感,上述测量电感电流瞬时值的方案不再适用,因此需要对原有电路拓扑进行改进。提出一种新型低感值准无桥APFC电路,并建立其小信号分析模型,采用单周期控制芯片IR1155S作为控制器,详细设计了电压外环补偿器,实现了1.0 kW准无桥APFC电路,实验验证了新电路的正确性。Single-phase traditional bridged active power factor corrector(APFC)can use the voltage drop of shunt resistor to reflect the instantaneous value of inductor current for current inner loop control.This method can be directly used in quasi-bridgeless APFC.The high frequency development trend of APFC requires the use of low inductance AC inductors and the above scheme for measuring the instantaneous value of inductor current was no longer applicable.So the original topology needs to be improved.A quasi-bridgeless APFC topology suitable for low inductance was proposed.After establishing small-signal analysis model of the topology,the voltage compensator was designed based on one cycle control chip IR1155S.Finally,the 1.0 kW quasi-bridgeless APFC was realized and experiments verify the correctness of the new circuit.
