Efficient resonant-type transformer inrush current limiter PROJECT TITLE :Efficient resonant-type transformer inrush current limiterABSTRACT :This study presents a new structure of a solid-state inrush current limiter (SSICL) to mitigate the inrush current of transformers. The proposed SSICL encompasses a series??parallel resonant structure that's shaped by 2 resonant circuits tuned at the provision frequency. During the energisation of transformers, the SSICL offers very high impedance by the parallel resonant circuit; thus inrush current is dramatically reduced. Below traditional conditions, an SSICL exhibits very low impedance through the series resonant circuit. By energising the transformer, an auto-triggered silicon-controlled rectifier (SCR) circuit inserts the parallel resonance circuit within the transformer input terminals. As well as the self-controlling capability, the proposed SSICL can be triggered by an external command. This effective remedy assures the right operation of the transformer protection system. So with a very easy structure, it has a fast and reliable performance in addition to full management capability. A prototype single-part SSICL is simulated by electro-magnetic transient program (EMTP) and tested. The simulation and experimental results show that the proposed SSICL significantly reduces the inrush current during the energisation method of the transformer. Did you like this research project?
