In the voltage inverter, the charge pump capacitor, C1, is charged to the input voltage during the first half of the switching cycle. During the second half of the switching cycle, its voltage is inverted and applied to capacitor C2 and the load. The two most common switched capacitor voltage converters are the voltage inverter and the voltage doublercircuit shown in Figure 4. In the voltage inverter, the. . This work introduces an 11-level switched-capacitor multilevel inverter (SCMLI) designed for solar photo-voltaic (PV) applications, capitalizing on the growing popularity of multilevel inverters due to their superior power quality. 67-times boosting capability, the proposed SCMLI employs. . At last, an inverter prototype with a 1 kW power rating is built, and the obtained results demonstrate that this inverter possesses the following superiorities: a wider range of output voltage, automatic balancing of the capacitor voltage, less current distortion, and high-eficiency power. .
