Abstract：In order to extend the operating range and maintain the linear control characteristics, a new type of saturable-core controllable reactor(SCCR) is designed and researched based on the theory of magnetic amplifier. An air gap is inserted in the ferromagnetic core to improve the linearization of the saturation characteristics. The magnetization mechanism and characteristics are studied. The magnetic flux distribution of the reactor is analyzed by using the three-dimension finite element method (FEM). On the basis of above research, the equivalent magnetic circuit model is built incorporating the magnetic flux leakage. The linear operating range of the new type of SCCR is increased and the capacity of DC source connected to the SCCR is also reduced. The simulation is compared with the prototype test results. The research results show that the equivalent magnetic circuit model is accurate. This has reference value in the design and application of the new saturable-core controllable reactor.
