Harmonic Analysis of Multi-pulse Converters under Varying Conduction Angles

摘要

Today, it is fact that Power Quality assures the fitness of electrical power that is being consumed by the devices interacting to it. This paper presents the modeling, simulation and harmonic analysis of multi pulse converters. Hence analysis has been done to observe the voltage and current harmonics of 6 and 12 Pulse controlled and uncontrolled converters. MATLAB (Simulink) is used for Simulation and analysis. Obtained results are compared to one another to get an authentic conclusion. Analysis is carried out with the help of Fast Fourier Transform (FFT) and THD results are obtained at different pulses with brief overview of waveforms generated in conversion process. Results of simulations pertaining to Harmonics for each condition is explored.
