Paper Title
Twelve Pulse Converter with Differential Delta Connected Transformer Arrangement with Reduced KVA Capacities for Line Side Harmonic Reduction
Authors

Abstract
now a day Harmonics is one of the most severe problems in variable frequency drives and in electrical network. Harmonics are generated due to switching action of the power electronics converters, which are known as non-linear loads. It’s required to reduce this harmonics up to certain level. In this work differential delta connected transformer with different winding connection to get 30 phase shift with reduced kVA capacities are presented for harmonic current reduction. A twelve-pulse AC to DC rectifier is proposed employing only 0.18 (pu) transformer kVA. The 5th and 7th harmonics are absent in the utility line current. For high current application parallel operation of two rectifier bridges with inter-phase transformer is analyzed

Keywords- Delta-connected auto transformer, kilovolt-ampere rating, multi-pulse rectifier, inter-phase transformer
