The basic structure and operation principle of the magnetically saturated controllable reactor are introduced in this paper. By introducing concept of switching function, the running status of reactor is analyzed according to the Kirchhoffs law of circuit and magnetic path. A design method for magnetically saturated controllable reactor is proposed which is based on the equivalent physical model. The design steps for the singlephase magnetically saturated controllable reactor are offered. And then a small-capacity experimental prototype is designed. The experiment results demonstrate the correctness of the proposed design method for the magnetically saturated controllable reactor. The design method is proved to be simple and accurate by the sample and also helps to the research and design of the magnetically saturated controllable reactor.
