In this paper, a new structure for a multilevel inverter based on the switched capacitor is presented. The proposed sub-module with one source and one capacitor is able to generate 5 voltage levels at the output, in addition to this, the proposed cascade structure with two isolated DC voltage sources along with two capacitors is able to generate 25 voltage levels at the output. Also, this structure is able to increase the input voltage using a capacitor. The proposed structure is able to charge the capacitor without using a sensor, in other words, the proposed structure is self-charging. In addition to working separately from the grid, the proposed structure can also be used connected to the grid for photovoltaic applications. To confirm the proposed structure, a quantitative comparison with similar structures has been done. In addition, a heat loss simulation has been done for the proposed structure. The simulation results confirm the functionality of the proposed structure.
