Power electronic converter is known as nonlinear device. Due to its conversion characteristic it drags and draws the source current from the power source. These characteristics make it to generate harmonics that will degrade the grid power quality (PQ). The effects of harmonics include malfunction of connected sensitive equipment such as protective relay and overheating of winding equipment like transformer...
This paper presents the design and analysis of an autotransformer based 24-pulse rectifier. The proposed ac-dc converter is based on a star connected autotransformer, designed for producing 15-phase shifted ac voltages for 24-pulse rectifier for effective harmonic reduction. Compared with 3-phase rectifier, the proposed 24-pulse rectifier can reduce the equivalent capacity of transformers and realize...
