In this paper, Power factor correction circuit of single-phase three-level boost converter is proposed. The advantage of the proposed control scheme for three-level boost converter are low blocking voltage of each power device, low THD(Total Harmonic Distortion) and high power factor. The control scheme is based on the current comparator, capacitor compensator and region detector. In simulations, the proposed system is validated.
