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 2):
The impedance matching device for matching the RF supply side impedance to the load side impedance according to  claim 1 , comprising,\n the variable reactor having the main winding and the control winding being wound around the core, and rendering inductance to be variable according to variation of the generated magnetic field that is generated by the control current passing through the control winding, and a control current forming part configured to form control current to be applied to the control winding, wherein, the control current forming part comprises, an operation part configured to compute a deviation signal that converges to a control settled value for settling a deviation component between the control target value and the feedback value for impedance matching, and a control current generator configured to generate the control current having a current direction determined on the basis of positive and negative properties of an AC signal being a control variable of the operation part, and current amplitude determined on the basis of amplitude amplification of the AC signal, wherein, impedance matching is performed by inductance variation in the variable reactor according to the control current.
