In this work, a seven-level switched capacitor boost inverter (7L-SCBI) is proposed with minimal resource count. The proposed inverter requires only eight switches and two capacitors to generate a seven-level voltage. The proposed 7L-SCBI is capable of generating a multilevel voltage as well as boost the input DC-link voltage up to 1.5 times with a reduced blocking voltage of switches and capacitors. The comparison in terms of efficiency and device count with other switched capacitor topologies is presented in detail. The performance validation of the proposed 7L-SCBI is done with the help of a laboratory prototype.

具有最少半导体器件数量的7L-SCBI拓扑

在这项工作中，提出了一种具有最少资源数量的七级开关电容器升压逆变器（7L-SCBI）。拟议的逆变器仅需要八个开关和两个电容器即可产生七电平电压。拟议中的7L-SCBI能够产生多电平电压，并通过降低开关和电容器的阻断电压将输入直流母线电压提升至1.5倍。详细介绍了效率和器件数量与其他开关电容器拓扑的比较。建议的7L-SCBI的性能验证是在实验室原型的帮助下完成的。
