A Novel Sliding Mode Control Strategy of the Grid‐Connected Inverter Under Unbalanced Grid Voltage

open access: yesIET Smart Grid, Volume 8, Issue 1, January/December 2025.
The manuscript presents a novel sliding mode control strategy of the grid‐connected inverter to achieve the objectives of maintaining DC voltage stability and suppressing negative sequence current under unbalanced grid voltage. The novel sliding mode control strategy can improve the system response speed and weaken the inherent chattering of the SMC ...
