Embodiment 1
[0037] Embodiment 1, as shown in FIG. 6, the power factor correction circuit using the harmonic current suppression method has a bridge rectifier 2 connected across the input end of the AC power supply 1, and a bridge rectifier 2 connected in series at the output side of the bridge rectifier 2 in sequence. Reactor 3, rectification and filtering device 5 and load 6.
[0038] A switch 4 is designed across the positive and negative ends of the bridge rectifier 2, a zero-cross detection device 11 connected to the AC power supply end, an overcurrent protection device 12 connected in series between the switches 4, and a switch 4 connected to the DC side The voltage detecting device 7 is connected to the switch driving device 9 of the switch 4 , the current detecting device 10 , the MCU chip 8 and the storage device 13 .
[0039]In the described harmonic current suppression method, when the input voltage is at the zero-cross point of the positive and negative half cycles, that is, wh...
