Comparative Analysis of Three-Phase Photovoltaic Inverters

3.1 Sinusoidal Pulse Width Modulation Approach. The most common method for operating single-phase inverters, especially three-phase inverters, is sinusoidal pulse width modulation. To calculate the closing and opening timings of switches in real-time, this command relies on the intersections of a sinusoidal modulating wave and a usually triangular carrier wave.
