This paper proposes an open switch faults detection and localization algorithm for shunt three
phase active filter topology. It mainly details converter configuration and examines a simple and
reliable optimised fault diagnosis method. The con verter topology is based on classical three-leg
active power filter topology. A ne w fault diagnosis method is proposed, based on classical
currents measurements. It includes combinatory logic to analyse and validate error signals. A
Hysteresis Control is applied before and after fault detection, which avoids any controller
reconfiguration. Simulation results obtained with Matlab/Simulink/Plecs tools prove the
effectiveness of this method.
