Analysis of a switched-reluctance generator for maximum energy conversion

Abstract

A successful analytical expression for maximum energy conversion in terms of DC-bus voltage, shaft speed and turn on/off angles of a Switched Reluctance Generator (SRG) based on self-excitation mode, single pulse operation is presented. The proposed analytical model, which can describe nonlinear of the magnetic characteristics of a SRG with sufficient accuracy, is the key used to derive the relation of maximum energy conversion with those control variables. The optimal ratio of DC-bus voltage over shaft speed, and excitation angle are proposed. Simulation and experimental results are provided to validate the analysis.
