Paper title: OPEN SWITCH FAULTS DETECTION AND LOCALIZATION IN THREE PHASES SHUNT ACTIVE POWER FILTER
Author(s): TARAK BENSLIMANE,
Abstract: 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 converter
topology is based on classical three-leg active power filter topology. A new 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.
