: Systems must follow many requirements, such as good efficiency, reduced cost and complexity and, most importantly,
improved ability. This is generally achieved before the inversion stage by using the front-end dc-dc booster (BC) converter,
leading to a two-step design. In the meanwhile, in terms of reducing the sophistication and volume of the whole system, singlestage power conversion systems that conduct the boosting process during the inversion step have some possible benefits. The split
source inverter (SSI) has recently been proposed in[1] as an alternative solution with some interesting features to the commonly
used Z-source inverter (ZSI) among many proposed alternatives. Taking into account that the SSI is regulated by a single
parameter, i.e. its dc. The modulation index controls the ac and ac sides, and it is of the utmost importance to investigate its gridconnected control function, which has not yet been examined.
