Fundamental principles, indices of performances and circuit structures of reducedvoltagestarting through thyristors are described in the paper.

Then the model is applied to simulate the direct start-up process, the reducedvoltagestarting process and the starting process with series resistance in the armature circuit.
Through comparison among direct starting, conventional reducedvoltagestarting and electronics starter, this thesis described starting mode, run mode and application location of soft starter.
