Development of multi-winding-transformer assisted diode converters for improved utility interface

Abstract

This paper presents a development of multi-winding-transformer assisted converters for improved utility interface. The proposed system is 96 pulse AC-DC converter which consists of two parallel connected 24-pulse AC-DC converters together with eight phase shifted diode bridges. Other than that, an Interphase transformer and a Zero sequence blocking transformer arrangements are used. The proposed converter is simulated, and results are presented and analyzed in this paper. Power quality aspects relevant to the proposed converter are improved. Furthermore, from acquired results, viability of the proposed system is ensured for its applications.
