Characteristics analysis of PFC boost converter with soft switching for harmonics reduction

This paper proposes PFC boost converter with soft switching for harmonics decrement and analyzes characteristics of PFC boost converter. In this technique power factor correction(PFC) is usually obtained by operating the PFC stage in the discontinuous current mode(DCM) Switching devices are operated for reducing current stress and electronical noise. As a result eliminate 3rd harmonic component and high power factor(PF) of the input line are verified by characteristics analysis and experimental results.
