A Review of Multi-pulse AC-DC Power Converters

This paper presents a detail investigation of different types of the converter with and without the transformer from low to high voltage range, and different types of converter harmonic reduction techniques. It is well known that during power conversion some harmonics is generated that is very harmful to electrical equipment. In this work, some multi-pulse insulated gate bipolar transistor (IGBT) based power converter has been simulated with and without static filter capacitors. The performance among those has been compared. Main objectives of this work are to investigate a suitable converter with lower cost, complexity, total harmonic distortion (THD) and voltage/current ripple. Simulation work has been done by using MATLAB/Simulink environment and a dc motor is connected to output side as a load. The obtained results have been discussed in detail to justify the validity of the review result. Finally, some possibilities to improve this research have been mentioned.
