Analysis of a Switched-reluctance Generator for Maximum Energy Conversion

抄録

An effective analytical expression for maximum energy conversion in terms of DC-bus voltage, shaft speed, and turn-on and turn-off angles of a switched-reluctance generator (SRG) based on self-excitation mode and single-pulse operation is successfully presented. The proposed analytical model, which can describe the nonlinearity of the magnetic characteristics of an SRG with sufficient accuracy, is the key to derive the relation between maximum energy conversion and the aforementioned control variables. The optimal ratio of DC-bus voltage to shaft speed and excitation angle are proposed. Simulation and experimental results are provided to validate the analysis.
