Improving ADRC Strategy for DC-Link Voltage Regulation in PV Grid-Tied Four-Leg Inverters Using an Adaptive Nonlinear High-Gain Observer

In practical photovoltaic grid-tied four-leg inverter systems (PV-GTFLIs), changes in radiation, temperature, and grid voltage magnitude cause significant disturbances, including DC-link voltage disturbance and power unbalance, which can impact the system’s dynamic responses, con...
