Small-Signal Modeling of Single-Pulse-Operated Switched Reluctance Generator and Its Verification

This paper proposes a small-signal model of single-pulse-operated switched reluctance generator (SRG). The small-signal model consists of mathematical expressions of the partial derivative of per-phase average dc-bus current with respect to control angles. The proposed partial derivatives are determined online using measured/simulated phase current and dc-bus voltage. During a simulation or an experiment, these partial derivatives are not directly measurable quantities; therefore, for the purpose of validation, a method to determine these partial derivatives (in post-processing) is also presented. Using this method, the proposed small-signal model is validated at several values of control angles through simulations and experiments.
