    Abstract

    The bridgeless power-factor-correction (PFC) converter possesses higher efficiency than the conventional boost-type PFC converter due to its reduced conduction voltage drop and conduction loss. The conventional multiloop control needs to sense the input current to yield the desired sinusoidal current waveform. This paper presents a control method for bridgeless PFC converter to provide sinusoidal current without sensing input current. The performance of the proposed method is demonstrated by the provided results with a 600W prototype.
