Abstract
In this study, a 13-level switched-capacitor inverter with triple voltage gain is proposed. The proposed structure generates 13-level output voltage using only one DC source, eleven switches, and three capacitors. The capacitors have the capability of self-balancing without the use of additional circuits or complex control methods. 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 standing Voltage (TSV). Another advantage of the proposed structure is the non-use of any 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.
