Abstract :
Active power filter is an advanced power electronic device, which can be used for integrated compensating harmonics and improving power quality. A shunt active power filter using for three-phase four-wire system is introduced in this paper. The basic operation principles and structure are analyzed. This paper proposes the design of a shunt active power filter, which can be used under the condition of unbalanced and nonlinear loads. The main circuit is given and the control method is discussed. A 3 kW experimental prototype is built and the experiment results indicate that the active power filter has good performances.
