The flying capacitor inverter combines low semiconductor costs and gives a multi-level output with high output frequency and low dynamic losses. Although the input is only two level with no need for the enormous DC-link capacitor bank, the output is multi-level and the output frequency is a multiple of the switching frequency.
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.
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.
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 power 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.
