  • Switched-capacitor multilevel inverter with self-voltage-balancing for high-frequency power distribution system
    Patent number: 11251719
    Abstract: Switched capacitor multilevel inverter (SCMLI) configuration for high-frequency medium voltage applications is presented. A 5L-SCMLI basic configuration is further extended to 9L operation with a reduced number of active switches having self voltage boosting and balancing ability. Further, the proposed 9L-SCMLI is extended up to n level being considered as the basic configuration for the extension of horizontal extension (HE) and vertical extension (VE). A generalized switching table is provided for the proposed extensions. Design of the size of capacitor demonstrated for the proposed 9L-SCMLI.
