Control of a hybrid excitation synchronous generator connected to a diode rectifier supplying a DC bus

This paper deals with the modeling and the control of the hybrid excitation synchronous machine (HESM) connected to a diode bridge rectifier. The set is operating as a DC generator that supplies an isolated grid in embedded applications such as aircraft electrical power generation. Saturation effects have also been taken into account. The aim of the control is to maintain the DC bus voltage constant when the load and/or the speed of the rotor vary. Simulation results validate this approach.
