Abstract:
An impedance matching device comprising a variable reactor having a main winding and control winding, wherein a generated magnet field in the core is an AC magnetic field with a magnitude exceeding a value to settle a deviation between a control target value for impedance matching and a feedback value, by changing the magnitude of the generated magnetic field by changing a control current passing through the control winding, thereby controlling inductance of the variable rector to be a predetermined value to perform impedance matching, the response delay in the impedance matching is reduced by reducing a response delay in the inductance variation of the variable reactor.

Claim (Index 3):
The impedance matching device according to  claim 2 , wherein,\n the operation part configures a double loop control, comprising; a first arithmetic circuit constituting a major loop on the basis of a difference between the control target value for impedance matching and the feedback value for impedance matching, and computing the control variable according to the major loop, and a second arithmetic circuit constituting a minor loop on the basis of a difference between the control variable of the first arithmetic circuit and a feedback value of the control current, and computing amplitude of the control valuable by the minor loop, so as to obtain a control current command, and the control current generator switches current directions of the control current on the basis of positive and negative properties of the control variable, and generates the control current whose amplitude is determined on the basis of the control current command.
