In this paper, considering the nature of switched-capacitor inverters and their primary challenges, an 11-level structure with a boost factor of 2.5, along with reduced voltage and current stress, is proposed. This structure requires a single voltage source, 10 switches, 3 capacitors, and 2 diodes.
One of the key parameters in designing a multi-level switched capacitor inverter is selecting the appropriate capacitor size for the structure being used. If the capacitor size is less than the correct and suitable value, the voltage ripple across the capacitor will increase.
One of the most important advanced and efficient technologies in converting DC electrical energy to AC is switched-capacitor multilevel inverters with reduced charging current, which enable output voltage boosting. This paper proposes a structure based on the switched-capacitor technique.
In general, switched-capacitor inverters are classified based on the output voltage levels and the voltage boost capability. Some structures generate voltage levels using an H-bridge, while others do not require an H-bridge.
