Abstract
This paper discusses a new configuration of the switched-capacitor multilevel inverter (SCMI). Similar to conventional multilevel inverters, the features of the proposed SCMI are the same with the multilevel inverters but uses less number of active switches than the other multilevel inverters have the same number of levels output voltage. As a result, the cost and size of the system are reduced compared to the previous configurations. In the proposed topology, the capacitor voltage can be self-balance without using any auxiliary circuit. By using the capacitor, the output voltage is stepped up from the input voltage and without employing transformer. To verify the operation principle, PSIM simulation is performed for 9-level onfiguration. The experimental results are also shown with 9-level inverter configuration.
