A Comparative Study of Sinusoidal PWM and Third Harmonic Injected PWM Reference Signal on Five Level Diode Clamp Inverter

This paper present the comparative modulation of Sinusoidal PWM and Third Harmonic Injected PWM Reference signal with carrier signal PD, POD, and APOD on 5 Level Diode Clamp on a R-L load. All of process are simulate with computer program MATLAB/Simulink. The result of simulation has shown value of THDV line-line output voltage on both SPWM inverter and Third Harmonic Injection modulation inverter with PD carrier signal generate a minimum THDV.
