Design and Simulation of Dual-Closed-Loop Control System for Three-Phase Inverter

As the core device of the new energy production system, the grid-connected inverter plays a crucial role in transforming new energy into electrical energy. Regarding the grid-connected three-phase inverter, the mathematical model of the two-phase rotary coordinate system is initially constructed. Subsequently, the double closed-loop control strategy is employed, and the simulation results validate the correctness and efficacy of this control strategy.
