Abstract

In this paper, a single stage flyback pfc converter is used as a power supply of a testing distance relay system. The flyback pfc converter topology, operation and control are presented. A fast and robust sliding mode control of the input current is also presented. The sliding mode controller enables also high power factor and nearly sinusoidal input current. The dc output voltage of the converter is controlled by a proportional integral (PI) controller. Simulation and experimental results from a laboratory prototype are presented and discussed.
