Bridgeless boost power factor correction circuit for constant current input

摘要: The present disclosure provides techniques for power factor correction on a constant current system without the use of diode rectifier bridge. In an example embodiment, circuit which includes two switching MOSFETs biased in opposite directions operate during half cycles input current. generates voltage to match phase is generated via charging and draining capacitor by MOSFETs. are driven duty cycle synchronously associated with wave form.
