###### Abstract
A shunt active filter is built to keep the system's actual power flow unimpeded.Moreover, the topology has an advantage in terms of ability enhancement.A three-phase hybrid cascaded modular multilevel inverter topology is presented in ref. [18]. Because of the benefits offered by the topology, the number of power switches, losses, installation space, voltage stress, and cost of the converter are all reduced. It enables transformerless operation for renewable energy environments, such as photovoltaic (PV) systems connected to a microgrid system, which optimizes power quality and improves reliability. In ref. [19], a single-phase 13-level switching-capacitor multilevel boost inverter (SCMLBI) with fewer switches and a voltage boost gain of six times is given. The primary objective of this research is to demonstrate a single DC source SCMLBI topology, which, when coupled with an appropriate sinusoidal pulse modulation (SPWM) approach, is capable of producing an AC output voltage that has a low level of harmonic distortion. The SCMLI given in refs. [20; 21] requires more switching to generate five levels. This topology has a smaller part count, and a higherlevel output can be achieved by cascading upgraded HB modules. There is only one isolated DC power source employed. Although an asymmetrical design generates more levels than a symmetrical operating mode, the easily available DC sources of varying magnitudes remain a worry even though an asymmetrical configuration generates more levels. Therefore, single-phase topologies are being advocated, since they are capable of functioning in either arrangement. Ref. [22] outlines an asymmetrical structure, which has a lower source count than previous models. These single-phase topologies can also be run in three-phase mode. Compared with traditional topologies, the switch count and gate drive count of the three-phase hybrid cascaded modular multilevel inverter (HCMMLI), which is described in ref. [18], are both significantly decreased. In ref. [23], there is a presentation of a single DC source hybrid seven-level three-phase architecture, which uses a hybrid control technique to increase efficiency. Ref. [24] presents a proposal for a three-phase symmetrical architecture, which uses fewer components. An improved control approach for renewable energy resources in microgrids that are gridconnected via voltage-sourced converters (VSCs) is provided in refs. [25; 26; 27; 28]. Ahigh-gain SC capacitor scheme with 13 stages is described in ref. [29]. One of the main problems with this design is that one capacitor is being utilized to charge another capacitor. To address the aforementioned issues, this study offers a new three-phase MLI design, which possesses minimum switching components, reduced voltage stress, and the ability to step up the input voltage. The assets of the proposed topology (PT) are as follows:  
1. The topology has voltage boosting capability. 2. Capacitors are inherently self-balanced. 3. Reduced voltage stress across the switching components. 4. It requires only an isolated DC source for the generation of five-level (line-to-line) voltages. 5. The minimum number of switches is ensuredfor any level of generation. 6. It can be operated for a wide range of power factors. 7. The suggested topology provides a lower TSV value, lowering overall costs. The following structure guides this paper. Section 2 discusses the specifics of the design, the underlying operating principle, and the recommended range of capacitance values. Section 3 discusses the modulation strategy of the proposed topology in detail. An evaluation of the power losses in the SC topology is presented in Section 4. Section 5 provides a comparative analysis with state-of-the-art topology to demonstrate its usefulness. Section 6 presents the results of the simulations and the experiments. Finally, Section 7 discusses the conclusion part of the proposed topology.
