Grid-Side Structure of PMSG: Inverter, PWM Generator, and Voltage Vector Control

The grid-side structure of PMSG comprises an inverter, PWM generator, and voltage vector control. It employs a dual closed-loop control strategy with an outer voltage loop and an inner current loop. For current controller design, the implementation requires achieving zero steady-state current error while ensuring minimal current overshoot during dynamic regulation in permanent magnet synchronous generator wind power systems.
