A Review on Transformer - Less UPFC

This paper is a review of an innovative technique with a new concept of transformer-less unified power flow controller UPFC . The Transformer-less UPFC is based on two cascade multilevel inverters CMIs , which reduce the complexity of the circuit. The construction of the conventional UPFC consists of two back-to-back inverters which results in complexity and bulkiness which involves the transformers which are complication for isolation and attaining high power rating with required output waveforms. The proposed controller will reduce the cost and space as compared to the conventional UPFC. A multilevel configuration technique will be used to reduce the total harmonic content and thus increases the overall efficiency of the system. Shaikh Mohammed Tauseef | S. M.
