- This paper proposes a new single phase bridgeless AC/DC power factor correction (PFC) topology using SEPIC converter to improve the power factor due to non-linear loads connected and by reducing total harmonic distortion (THD) of the utility grid. By eliminating the input bridge in conventional PFC converters, the control circuit is simplified. The controller operates in multi loop fashion as the outer control loop calculates the reference current through innovative filtering and signal processing. Inner current loop generates PWM switching signals through the PI controller. Performance of the proposed PFC topology is verified using PSIM circuit simulations.
