PFC with Inductor Current Hysteretic Control and Voltage Fuzzy Controller for the Output Voltage

Abstract

The paper presents a PFC (power factor correction) that uses hysteretic control of the inductor current. The PFC uses a fuzzy controller to control the output voltage. The output voltage's ripple is smaller and the line current keeps sinusoidal shape with a dynamic's system much better. This controller is proposed to be implemented in a FPGA.
