Abstract :
A novel boost power factor corrector using a single switch is discussed. The new circuit is analyzed in steady state and experimental results obtained from a laboratory prototype are also provided. The novel converter has low current and voltage stresses and has a simple control loop to achieve near unity power factor with the aid of the commercially available chip UC3854. Another advantage of the converter is the ability to provide soft switching conditions for the diodes and zero-current switching for the active switch at turn-on using only one switch without increasing the component count
