This common grounding is precisely achieved by connecting the negative end of the input DC voltage and the grid neutral point. The circuit topology comprises 11 power switches, three switched capacitors, and two diodes, resulting in a lower switch count compared to the previous topology in [ 13 ].
The proposed inverter circuit depicted in Fig. 1 is a single-phase, nine-level switched-capacitor-based inverter. It consists of three units: a single-input DC source, an auxiliary circuit (a cascade charge and discharge circuit), and an H-bridge circuit.
These capacitors play a vital role in boosting the input voltage. Thus, the output voltage is equal to 2 vin, and each step has a voltage of vin /2. The switching capacitor C 1 is charged to its maximum input voltage, while the flying capacitors C 2 and C 3 are charged to 50% of the input voltage.
A single-phase, nine-level switched capacitor-based inverter topology is presented in this paper. The proposed circuit has the ability to generate a nine-level output voltage waveform with four times the peak-to-peak amplitude of the single-input DC voltage.
In recent years, the switched capacitor inverters (SCIs) have been paid more attention due to their inherent voltage boosting capability and higher number of output voltage levels. Such inverters are more suitable for medium voltage applications, including distributed power generation systems 1.
The switching capacitor C 1 is charged to its maximum input voltage, while the flying capacitors C 2 and C 3 are charged to 50% of the input voltage. Consequently, the capacitance value selection of these capacitors is more critical to achieving the 9L output voltage.
