| Abstract |
The loads on the electrical systems of automobiles are projected to increase significantly in the near future. This will result in a requirement for improved efficiency over the claw-pole or Lundell generators which to date have been employed in cars for approximately twenty years. The alternative system proposed in this paper is based on a machine with two sets of stator windings, for power generation and excitation respectively, and a cage-like rotor without electrical contacts. Regulation of the output voltage is provided by a pulse-width-modulated converter operating with adjustable magnitude and adjustable frequency and with reversible phase sequence for operation over a wide speed range. The system design is examined and test results from an experimental prototype are compared with both model predictions and the performance of a conventional generator. |
