Abstract :
A ZVT boost converter is embedded in a power factor correction system. The control circuit of the converter assures soft-switching for all the MOSFETs and load regulation. The PFC system contains additional control circuits which assure: (a) the input current follows the input voltage in a sinusoidal form; (b) feedforward line voltage regulation; (c) overcurrent protection at the input of the converter; (d) overvoltage at the load. The main chip in the control system is a UNITRODE controller of type UC3855BN. The designed system features high power factor correction, good line and load regulation and high efficiency
