Abstract :
A method for modeling permanent-magnet AC generator systems with electronically switched loads is presented. Continuous switching of the associated power electronics results in continuous change in the machine system topologies. The network modeling of such systems was done on an instantaneous basis in the time domain. In this approach, the effects of magnetic circuit nonlinearities and space harmonics due to stator slotting and rotor saliency were taken into account. This generalized method was used to predict the dynamic performance of a two-pole, 75 kVA, 208 V, 24000 rev/min permanent-magnet generator system, as well as to study the effects of electronic component failure and the effects of damping circuits on the system power
