Comparative Analysis of Multi-Pulse Controlled Converters using Zigzag Transformers
Amit Kumar, Saurabh Gupta
This paper presents a thyristor-based controlled 18-pulse AC to DC converter zigzag Phase-Shifting double winding transformer (a three-phase transformer with a primary winding connected in an associated zigzag setup and a configurable secondary winding). The 18- pulse AC - DC converter is liked to develop swell variables further, confined primary and secondary windings keep up with separation, and voltage guidelines can be maintained by adjusting the firing angle point of the thyristor, so the proposed work is helpful where smooth, and directed. Separated power is required. This approach eliminates the intricacy required to design complicated autotransformers or isolated multi-winding transformers used with other systems. The paper additionally presents the examination of 12-pulse and 6-pulse AC - DC converters for various boundaries like wave factor, harmonic distortion in input current for unbalanced supply voltage, the efficiency of the converters, and power factor variations of input power supply. All these parameters are compared for no-load light loads and full-load conditions. We further broaden our recreation for estimating the impacts of channels like L, C and LC in the simulation results, showing some beneficial and exciting results.
