PROBLEM TO BE SOLVED: To provide a saturable inductance having little loss by winding a primary circuit winding and a secondary circuit winding which consitute a saturable inductance, around a polar core connecting the primary circuit winding in parallel, winding it in the opposite direction, and connecting a capacitor in series with the saturable inductance. SOLUTION: A saturable inductance between terminals 71 and 72 includes a first winding 73 and a second winding 74, which are connected in parallel and wound in the opposite direction, on two parts 75 and 76 constituting a magnetic circuit. A secondary circuit consists of a single winding 77, connected with a current source, which consists of a DC power supply 78 generating a voltage V and a series resistor R. A current I generated from the current source flows through a winding 77 which is common to the two parts 75 and 76 of the magnetic circuit. A saturable inductance capable of adjustment merely by changing the current I can be obtained. |
