The increasing demand for compact, efficient, and reliable power conversion structures, especially for photovoltaics, has promoted the development of sophisticated single-stage inverter topologies such as split source inverter (SSI). In this study, improving the performance of dual input split source inverters (DSSI) is targeted at utilizing a sophisticated modulation scheme. The DSSI integrates dual input sources with a split-source inverter structure, providing continuous DC input current, reduced voltage stress, and stable DC-link voltage, which are essential requirements in such applications. The proposed control strategy uses sinusoidal pulse width modulation (SPWM) and optimized simple boost SPWM (SB-SPWM) to control the output voltage and improve the system efficiency; by implementing these modulation techniques, the system offers better control of voltage gain and, in turn, exhibits better overall control of the inverter. The proposed SB-SPWM method is validated through a set of experiments with the conventional SPWM scheme.
