Purposes of PFC Control

Reducing harmonic current

This figure shows an example of using PFC Control ICs.

(Application Example)

This figure shows an example of current waveforms before and after harmonic current reduction.

Current Waveforms

  • Improves the power factor by reducing the harmonic content of a current.
    Stabilizes the AC input.

  • Stabilizes the PFC current.
    Enables a power supply circuit to keep a constant supply of a nearly perfect sinusoidal current.

This figure shows how power reduction is achieved with PFC control.
