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 4):
The impedance matching device according to  claim 3 , wherein,\n the first arithmetic circuit comprises either of the following control circuits; a proportional integral control circuit configured to output as the control variable, a proportional integral signal obtained by performing proportional integral control over a difference between the control target value and the feedback value for impedance matching, and an integral control circuit configured to output as the control variable, an integral signal obtained by performing integral control over the difference between the control target value and the feedback value for impedance matching, and the second arithmetic circuit comprises either one of the following control circuits; a proportional integral control circuit configured to output as the control current command, a proportional integral signal obtained by performing proportional integral control over a difference between the control variable of the first arithmetic circuit and the feedback value of the control current, and an integral control circuit configured to output as the control current command, an integral signal obtained by performing integral control over the difference between the control variable of the first arithmetic circuit and the feedback value of the control current.
