Active filter control using a sliding mode approach

Load distortion currents in the three phase system can be suppressed by employing active power filters. This paper describes a sliding mode control strategy of the three phase voltage source converter. The validity of the control circuit is verified by simulation results. Considering the new control approach, the dynamics of the active filter as well as its compensating characteristics are also analyzed through energy storage elements. The system performance is valid for steady and transient states in the three phase circuits.<
