Implementation of Modified Reference PWM forReducing the Harmonics in Inverters by usingMatlab/Simulink

[摘要] This paper attempts to analyse the dominant harmonics present in sinusoidal PWM inverter output with AC source . A new technique for reducing this harmonics in PWM inverter output by modifying the reference waveform is proposed, by using MATLAB simulations.
