Brushless Induction and Reluctance Generators with DC Excitation: Experimental Verification
Abstract:This article presents the steady-state performance of brushless induction and reluctance generators with DC excitation for the first time. The results are devoted to the experimental verification of such a new excitation principle. Similarity of these generators with the conventional synchronous generators is emphasized. The results show that the frequency of the generated voltage is directly proportional to twice the rotor speed, irrespective of the load and excitation conditions. To maintain the terminal voltage constant under varying load conditions, a voltage stabilizer is developed. Determination of maximum attainable power and critical load impedance are experimentally presented. Useful conclusions have been provided, which are considered to be a good aid for designing these generators.
