Inrush current problems of the industrial transformers are occasionally moreserious than the utility transformers. A new Solid-State Inrush Current Limiter(SSICL) is proposed for medium voltage power transformers. The SSICL consistsof three similar sets. Each set includes a bidirectional semiconductor switchand an inrush current limiter resistor. Using a control strategy based onKalman filtering, transformer inrush current is suppressed during magnetizationprocess. In fact, built up profile of the inrush current is dictated inaccordance with the estimated current by a slow dynamic Kalman filter. Asingle-phase prototype SSICL is developed and tested. The proposed controlscheme is simulated in MATLAB-SIMULINK. By using Real Time (RT) toolbox of theMATLAB software and a PCI_1711U, interrelationship between the SSICL and itscontrolling system is realized. Some experiments are carried out to evaluatethe performance of the SSICL. The results show that the proposed SSICL canconsiderably suppress inrush current of the transformer
