چکیده
This paper compares the performance of diode clamped three level inverter based STATCOM with sinusoidal and space vector PWM techniques. Space Vector Pulse Width Modulation (SVPWM) technique is the most advantageous technique than the conventional sinusoidal PWM technique for a multilevel inverter. The space vector pulse width modulation technique is an advanced, computation-intensive PWM method and is possibly the best among the all other PWM techniques. Unlike the conventional PWM method the space vector pulse width modulation technique produces lesser amount of harmonics. The total harmonic distortion (THD) of the output waveform is reduced by 47% than the sinusoidal PWM. The switching losses are reduced by 30%. The modelling of complete system is developed in MATLABSimulink. KeywordsSTATCOM, SVPWM, PWM, THD, IGBT
