Abstract

the differential mode converters are presented which offers can reduce the passive elements such as inductors and capacitors. This results in a reduction in the size of the device improve reliability and reduce the total cost. One of the most promising systems in differential mode converters is the Single-Ended Primary-Inductor Converter (SEPIC). SEPIC has some advantages over the other topologies including lower components and the ability of isolation by using a high-frequency transformer. It is worth mentioning that this model is one of the promising models in the use of renewable energy. On other hand, the Semi Z-Source Inverter (SZSI) is presented to reduce the count of components and work as a four-wire system. The system can be achieved by using three single-phase Semi Z-Source Inverter (SZSI). This paper presents a comparison study between two topologies. In addition, the comparison is achieved based on the voltage and current stress. It has been considered the dynamic response. The comparison is validated based on PSIM software.
