The Design And Analysis Of A High Speed High Voltage Pulsed Alternating Current Generator For A Self-contained Power System

The rotor of a homopolar inductor alternator can be made of a solid forging to withstand the thermal and rotational stresses of high speed and high utilization operation. This machine was researched for use in alternative energy schemes and high power application recently.In this paper, a high speed high voltage pulsed alternating current generator for a self-contained power system was designed and analyzed. Compared with the conventional alternator,homopolar inductor alternator was very suitable for the self-contained power system,for the solid forging rotor can run high speed, its moment of inertia is large, and its efficiency and power density are very high. As the self-contained power system required that the volume and weight of generator could not be too large, the way of how to design a high power density electric machine was studied. A slotless armature winding scheme was chosen for the homopolar inductor alternator, and high strength alloy steel was chosen for rotor material. For convenience of homopolar inductor alternator's control, the mathematics model of homopolar inductor alternator was established, and the calculation of inductance parameter was given.The main work of this paper is the electromagnetism design of homopolar inductor alternator and its performance analysis. Firstly, the research work already has been doen for homopolar inductor alternator was investigated, some usefull conclusion for the generator's design was adopted. And then the method of electromagnetism design was presented, an 8 pole pairs homopolar inductor alternator was designed. Lastly the performance of the homopolar inductor alternator was analyzed.
