Abstract

This paper proposes development of a Pulse Width Modulation (PWM) scheme that overcomes the weakness of conventional Carrier-Based PWM (CBPWM) performance on Neural Point Clamp Inverter (NPC).This scheme uses the conventional CBPWM technique to developed Advanced CBPWM.This technique uses triangular carriers in different amplitudes that are arranged in composition, then injects the modulated signal that has been decomposed with the third harmonic.The proposed PWM schema was verified using MATLAB/Simulink software.By applying this scheme, the quality of power, voltage and current are improved, and finally Total Harmonic Distortion (THD) can be reduced.
