Abstract
Conventional multi-level inverters such as neutral point clamped and flying capacitor inverters do not have boosting capability and self-balanced capacitor voltage. Thus, in this paper, we propose a novel three-level inverter based on switched capacitors to solve the above problems. The proposed inverter has lower voltage stress than the general switched-capacitor multi-level inverter. Meanwhile, an improved modulation strategy is adopted in the proposed inverter. The three-level space vector diagram is converted into a two-level one, and the space vector modulation is simplified. Then, we analyze the power loss and design guidelines for the device in the inverter. Finally, a corresponding simulation and an experimental platform will be established to verify the feasibility of the proposed inverter. The results prove that the proposed three-level inverter has good performance and dynamic response that meets the requirements.
