A simulation model for the saturable reactor

A simulation model for the saturable reactor, an electromagnetic devices widely used as a protective element for the thyristor circuit, is presented. The model has been simulated using an improved version of SPICE, which also contains the model of the single-core reactor (SCR), and has proved to be fast and accurate on practical cases. Examples given include an industrial chopper for an electric drive; the model of the saturable reactor has improved the overall simulation accuracy of the chopper.<>
