In this paper a 13-level switched-capacitor inverter with a voltage gain of 3 is proposed. The proposed structure generates a 13-level output using only one DC source, 11 switches, and 3 capacitors. The capacitors in the proposed structure, without the use of additional circuits or complex control methods, have the capability of self-balancing voltage. Additionally, the inrush current of the capacitors has been reduced using a soft charging method. The proposed structure has been compared with different 13-level structures presented in recent studies in terms of various parameters such as the number of semiconductor devices, the number of DC sources, voltage gain, Maximum Blocking Voltage (MBV), and Total Switching Voltage (TSV). Another advantage of the proposed structure is the non-use of a diode and its cost-effectiveness. In addition, the power losses of the proposed structure have been evaluated, and its efficiency has been calculated for various output powers. Finally, the performance of the proposed structure has been verified through simulation and laboratory implementation under both stable and various dynamic conditions.
