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 8):
The impedance matching device according to  claim 3 , wherein,\n the control current generator comprises a chopper circuit of full-bridge configuration including four switching elements, wherein, in controlling the amplitude of the control current that is applied to the control winding, the pulse width control is applied to open-close operations of either one of two switching elements, connected to either of the polarities, positive end and negative end, on the basis of the amplitude of the control current command, and switching of the directions of the control current applied to the control winding is controlled by the switching operation on the basis of the polarity of the control variable of the two switching elements that are connected to the other polarity.
