Abstract
A new control method for single-phase shunt active power line conditioners (APLCs) operated under zero average power consumption is proposed in this paper. The amplitude of the sinusoidal source current which is in-phase with the source voltage can be determined from the average value of the instantaneous load power. Then the command current for the shunt APLC is obtained by subtracting the source current from the load current. Neither bulky filter nor time-consuming computation is required. The shunt power compensator supplies all the harmonics of the load current and the source only supplies the fundamental component. Experimental results on a prototype verify the feasibility of the presented scheme.
