Split-Source Inverter using SPWM and THPWM

in electrical DC-AC power conversions, some applications need the AC output voltage to be higher than the input voltage. Thus single-stage DC-AC power converters are recently gaining higher popularity due to their features. They are in terms of size, weight, and cost. They are also less complex in nature. Different topologies exist, where the Z-source inverter, the buck-boost voltage source inverter, and the Y-source inverter are the common topologies. Another single-stage DC-AC power converter, named the split-source inverter (SSI) has some merits over the other topologies, the main being the possibility to use the common modulation schemes of the conventional voltage source inverter without any modi�cation. Here Sine PWM (SPWM) and Third Harmonic Injected PWM (THPWM) are given as the modulations and they are compared. The simulation is done in MATLAB/SIMULINK. The prototype of split-source inverter is setup and gate pulses are obtained from Arduino Mega2560.
