A Novel Critical Analysis Method of Homopolar Inductor Alternator for Preliminary Design in Capacitor Charge Power Supply

In order to realize quick preliminary design for capacitor charge power supply (CCPS), a novel critical analysis method of homopolar inductor alternator (HIA) is proposed in this paper. First, a specific base value system of CCPS is proposed for making the critical analysis method universally applied for different machine and charge parameters. Second, under the equivalent average-value phase model of HIA, a critical curve and a maximum power analysis method based on the curve are proposed. After that, an outline of the preliminary machine design under the critical analysis method is presented. Third, considering the salient rotor structure of HIA, under the equivalent average-value direct- and quadrature-axis (DQ) model of HIA, a critical map as well as its maximum power analysis method is proposed. In the end, for these two types of critical analysis method under different average-value models, each of their advantages and applications are discussed.
