In order to cover energy requirement, the photovoltaic is one of the proposed solutions. However, according to the aim of its utilization, the direct current output voltage of photovoltaic source should be adjusted. The boost inverter is a recent power processing stage that can increase, filter and alternate direct current input voltage. So as to control it, there are various modulation types. Among them, the sinusoidal pulse width modulation is presented in a new digital form. The operating principle of the aforementioned inverter and command have been analyzed and verified by simulation and realization. Furthermore, frequency analysis of output voltage signal proves efficient results.
