Control of a Hybrid Excitation Synchronous Generator for Aircraft Applications

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> This paper deals with the control of a hybrid excitation synchronous generator which is used to supply an isolated grid for aircraft applications. This grid is supposed to be a 270-V dc bus. Thus, a rectifier is required between the machine and the dc bus. A diode rectifier is preferred here due to its great reliability and because it is also a low-cost solution. A controller is then proposed in order to regulate the output dc voltage of the generator. It is finally validated by simulations and experimental results. </para>
