This paper presents two modern modulation techniques applied to three phase inverters from a hardware implementation point of view. The considered techniques are the sinusoidal pulse width modulation with zero sequence injection and the space vector modulation. Both these techniques conduct to the same result regarding supply voltage usage efficiency and harmonic content of the resulted signals. The implementation was developed in Matlab-Simulink, using the System Generator software, and validated through simulation. Both the modulation algorithms were implemented in hardware on a low cost FPGA, and the resulted designs are compared for resource usage efficiency, obtained speed and easiness of integration within a complex AC drive control system.
