Self-excited switched reluctance generator

This paper presents a study on the behavior of the self-excited switched reluctance generator (SSRG). Following an extensive bibliographic review about SSRGs, the mathematical model, principle of operation and simulation results of the generator dynamics is presented. A capacitor partially charged, in parallel with the load is used as a mean to provide the necessary amount of magnetic flux and start the generator´s voltage built up. The arrangement is such that the generated voltage and current is delivered to the load in D.C. mode. To correctly represent the self excitation operation the mathematical model must take into account the core magnetic saturation, and that is observed here. Experimental results are included to validate the discussions presented.
