Abstract
- Currently, many inverters employ inductors to boost the AC voltage. However, this leads to increased current distortion and limits the voltage boosting capability of the inverter. To address the above issue, a triple two-level inverter is proposed in this paper. The proposed inverter adopts a switched-capacitor boost circuit to boost the AC output voltage and to generate a multi-level voltage. Simultaneously, a three-phase full-bridge circuit is assigned to convert the DC voltage into AC voltage. In addition, a novel space vector modulation strategy is introduced to achieve capacitor voltage self-balance. Finally, simulation and experimental platforms have been established to verify the effectiveness of proposed inverter. The obtained results show that the proposed inverter meets the requirements for the expected inverter. [ABSTRACT FROM AUTHOR]
