Interline Power Flow Controller based on Multi Output Sparse Matrix Converter

A novel structure is proposed for Interline Power Flow Controller based on Multi Output Sparse Matrix Converter. The Multi Output Sparse Matrix Converter is first considered in this paper and has been used as IPFC instead of multiple inverters. The conventional IPFC contains a bulky capacitor in its structure that increases volume and cost of the system and since it has limited lifetime consequently it reduces reliability and life time of IPFC, but the new IPFC does not have those problems. Necessary information needed to simulate Multi Output Sparse Matrix Converter is presented. The new IPFC system is modeled and sliding mode controller is used to control line current in order to control line power. Sliding mode control is selected because of its robustness and fast response time. Sliding mode control is implemented in an improved manner. Finally, proposed IPFC is simulated in PSCAD/EMTDC software and output waveforms are compared with reference values.
