The most recent advancement in switched-capacitor boost inverters for high-frequency ac systems and solar PV utilization is their reduced component count. SC-based multilevel inverters (MLIs) are the ideal solution for PV applications since they have a larger voltage gain and a sensorless mechanism for self-voltage balancing.
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.
