Design & Simulation of Twelve Pulse Thyristorized Controllers in Series and Parallel mode of Operation

Abstract

Many industrial applications such as electroplating, electro refining, heating, air conditioning and even nuclear applications demands for high current and high voltage converters. Conventionally M6 converters are being used, faces limitations such as power quality, power factor and harmonics. In this paper an attempt is made to verify the performance of a twelve pulse thyristorized controller for heavy industrial applications over six pulse. The performance of designed twelve pulse high current thyristorized controller is verified with the extensive simulation work on R load. This paper also differentiate between the performance of series connected thyristorized controller and parallel connected thyristorized controller.
