Abstract
The synthetic circuit 16 synthesizes an offset voltage from an offset voltage generator 14 with a signal output from the other end of the first coil 15 and supplies the synthesized signal to the other end of the second coil 18 through an output matching resistor 17. A potential difference detection unit 21 detects a potential difference between both ends of the output matching resistor 17. A comparison circuit 23 outputs an overcurrent detection signal when a voltage value of a detection signal from the potential difference detection unit 21 exceeds a positive or negative threshold voltage. When the overcurrent detection signal is input, a control unit 24 turns off the switching means 19 and forcibly disconnects the synthetic circuit 16 from the output matching resistor 17.
