Abstract :
This paper presents the modeling and simulation of a variable-speed 12/8 switched reluctance generator (SRG) supplying 30 kW to a 540V DC bus in more electric aircraft power systems. The generator characteristics are studied by simulation over a large speed range using a nonlinear Simulink model based on the magnetization curves of the machine. A simple power control scheme is proposed in which the turn-on angle is kept constant while the conduction angle is used to control the DC output current. The SRG closed-loop power control performance obtained for the operating ranges of 5000-10000 rpm and 20-30 kW is presented to validate the proposed control scheme.
