| Abstract: | In this paper, a new control algorithm for active power line conditioner (APLC) is proposed. The proposed APLC contains two power converters, a series power converter and a shunt power converter. The series power converter is operated as a current source, and it has the function of a harmonic isolation to block the harmonic current from the nonlinear load to mains and the harmonic voltage from the mains to load. The shunt power converter is operated as a voltage source to supply a clean and regulated output voltage to the load. Both power converters use the same dc bus. To demonstrate its performance, a prototype is developed and tested. The tested results show that the proposed APLC has the expected performance. |
