The Uninterruptible Power Supply (UPS) is a kind of power supply with electric energy storage, but most UPS systems bring harmonic pollution to the grid, and the power factor is inaccurate in the boost circuit, the output voltage is unstable. Therefore, an active power factor correction circuit (APF...
