Unbalanced Loading Behaviour of the Isolated Interior Permanent-Magnet Generator

Abstract —Portable AC generators directly driving isolated AC loads require tight voltage regulation, good voltage waveform quality and high efficiency. This paper studies the performance of a 4 pole, 16 kW interior permanent-magnet generator under balanced 3ph and unbalanced 1ph resistive loading conditions. For the unbalanced 1ph condition, the use of star and delta winding connections is compared. The results of analytical and finite-element simulations have been compared with experimental results.
