Abstracts: In this project 12-pulse voltage source converter by using inverted sine pulse width modulation technique is modeled to eliminate the harmonic of the system produced by the non-linear load. For the harmonic elimination different methods are used. This project describes the operation of 12-pulse VSC with novel PWM technique. There are many Pulse Width Modulation Techniques are used to firing of Switching Devices like Sinusoidal Pulse Width Modulation, Space Vector Pulse Width Modulation, Delta Modulation etc. Here by using ISPWM technique we can achieve greater pulse area then conventional PWM techniques to re-duce the harmonics and switching losses.
