Abstract: A wide speed range permanent magnet synchronous generator (PMSG) system is studied in this paper, including the PMSG design and comparative study on control strategies with a pulse width modulation (PWM) rectifier, the purpose of which is to regulate the DC-link voltage. It is of great importance to study the foregoing DC power system based on the PMSG and PWM rectifier, where vector control (VC) can be implemented and the corresponding field-weakening strategy can be realized by injecting a field-weakening current component without any auxiliary devices. Large machine inductance is desired in order to limit the short-circuit current and the loaded voltage drop. Different control strategies including VC, direct torque control (DTC) and direct voltage control (DVC) are studied and compared with both simulations and experiments.
