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