EQUIVALENT CIRCUIT OF THE SWITCHED RELUCTANCE GENERATOR BASED ON THE DC SERIES GENERATOR

Martin Lipták - Valéria Hrabovcová - Pavol Rafajdus

   In this paper equivalent circuit of the switched reluctance generator (SRG) will be derived on the base of DC series generator scheme. Equivalent circuit of SRG with the most often employed asymmetric half-bridge power converter (APC) has only one possible current path in the circuit analogous to the equivalent circuit of the DC series generator. Then no-load and short circuit states of the SRG will be defined. The mathematic model of single-phase SRG cooperated with APC will be developed based on the equivalent circuit. The SRG operation will be simulated and then the results verified by measurements on 3-phase 6/4 low power SRG. The generator controlled with DSP will be tested under various load and speed conditions.
