Implementation of shunt active power filter with comparative study of SPWM and SVPWM technique for reduction of THD

摘要

This paper presents a comparative study of two different PWM techniques, i.e. the sinusoidal pulse width modulation (SPWM) technique, and the space vector pulse width modulation (SVPWM) technique for three phase H bridge inverter with shunt active power filter (SAPF) to reducing the total harmonic distortion in a non linear loads.In conventional diode clamped inverter required balancing circuit and extra diodes for clamping. In proposing H bridge inverter no extra diodes and balancing circuit are required and reduce the complexity and cost. The performance of SPWM and SVPWM technique is analysed by using MATLAB / Simulink software. Keywords: Shunt active power filter (SAPF), H- bridge inverter, sinusoidal pulse width modulation (SPWM) technique, Space vector pulse width modulation (SVPWM) technique, total harmonic distortions (THD).
