In many applications, the cascaded multilevel inverter (CMI) topology is common. However, the CMI's biggest disadvantage is that it necessitates numerous switches and segregated dc sources. As a result, the CMI topology becomes more expensive, complex, and large, and its efficiency suffers. Compared to the conventional CMI, the proposed inverter uses almost half the number of switches, while maintaining a boosting capability. Additionally, the main drawback of switched-capacitor multilevel inverters is the capacitor inrush current. This problem is also averted in the proposed topology by using a charging inductor or quasi-resonant capacitor charging with a front-end boost converter with a L-C filter. The capacitor will enhance the diode current while decreasing the ripple voltage. This high current could harm the diode, exacerbate the heating issue, and reduce the filter's effectiveness. On the other hand, a straightforward series inductor lowers the output voltage and current's peak and effective values. An ideal practical filter circuit can be created by combining the functions of a series inductor filter and a shunt capacitor to stabilize voltage and smooth current, respectively. The effectiveness of the suggested inverter topology is confirmed by simulation results.
