Abstract

Power electronic loads inject harmonic currents into the utility system. The large increase of power consumption will inevitably lead to deteriorating power quality due to the popularization of switch-mode power electronic equipment. In this paper, a periodic voltage is injected in the control circuit to vary duty cycle of the rectifier switch within a line cycle so that the fifth-order harmonic of the input current is reduced to meet the IEC 61000-3-2 requirement. Experimental results are presented to confirm the validity of this method.
