Simulation of Switched Reluctance machine with the operation at four-quadrant

An nonlinear simulation model of the Switched Reluctance machine with the operation at four-quadrant founded on MATLAB is presented. The simulation of the prototype with three given rotor speeds and four different loads are made. The simulated results on the rotor speed curves, the rotor speed ascending time and the phase current waveforms are given. It is shown that the operation of the Switched Reluctance machine at four-quadrant and the conversion course can be simulated efficaciously by the model. There is the impact phase current during the conversion course at four-quadrant. The phase current of the Switched Reluctance machine with the operation at four-quadrant is unipolar so that the unipolar power converter is need.
