Abstract:
A constant current control circuit with PFC function and its PFC circuit are provided. The PFC circuit comprises a valley-filled PFC circuit and a harmonic compensation circuit, whose output signal is supplied to the current control circuit. By adding the harmonic compensation circuit to the PFC circuit, the distortion of input current is decreased and the power factor is enhanced. Moreover, the whole circuit is simplified and its cost is reduced.
