Nowadays, the uninterruptible power supply (UPS) is important in reliability for electric device. The UPS need high quality electricity. Therefore, the simulation of the three-level sine-wave inverter with power factor correction (PFC) is proposed in this paper. Moreover, the circuit’s guidelines of the active PFC controller in the active PFC and the sinusoidal output voltage are also presented. Validity of the proposed the three-level sine-wave inverter with the active PFC is confirmed by simulation. The simulation results show the very small current harmonics, the input power factor most nearly unity and constant output voltage when the suddenly step-load changed.

The fundamentals of power factor correction The fundamental issues of power factor analysis for non-sinusoidal waveforms are described. A full-wave rectifier circuit is analysed and original approximations are derived for voltage ripple, peak diode current and input power factor. A power factor correction technique, based on a switching mode power supply, is presented.
