Control of a 750kW Permanent Magnet Synchronous Motor

Permanent magnet synchronous motors have been widely used due to their high performance and high efficiency. In this paper, we talk about the control of a 750kW permanent magnet synchronous generator which is used for a hybrid turbocharger for a marine application. The controller outputs regulated 700V dc bus voltage with a voltage variation of less than 5% under 100% load transient condition to ensure that the inverter which relies on this 700V input will provide stable three-phase ac power output. The system overview, control methodology and control simulation using atlab/Simulink is provided in detail. The tests and simulation results are also provided and compared to show the validation of the simulation model and the performance of the generator control and dc bus regulation.
