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.
Inverters act as intermediaries, converting the voltage generated by renewable energy sources into AC voltage compatible with the electrical grid. In general, inverters are categorized into two types based on their output voltage levels: two-level and multilevel inverters.
Notable features of multilevel inverters include improved voltage and current waveform quality, lower harmonic interference, higher reliability, increased efficiency, reduced electromagnetic issues, and lower component stress 1, 2, 3.
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.
Our solar PV systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
