。[Claims for Utility Model Registration] A high voltage and current detection circuit that measures the output current of a power amplifier in a high voltage generation circuit configured at least in a current feedback type, the current being connected in series to the output side of the power amplifier. In a high-voltage current detection circuit that detects the output current of the power amplifier by detecting the voltage generated in the detection resistor, a high-voltage floating power supply is supplied and the voltage generated in the current detection resistor is differentially amplified. a high-speed A/D converter that is supplied with a high-voltage floating power supply and that converts the output voltage of the differential amplifier into a digital signal at high speed; and a digital output of the high-speed A/D converter. The high-speed D/A converter comprises an isolator that isolates and transmits from the high voltage system to the normal signal system, and a high-speed D/A converter that quickly converts the output signal of the isolator into an analog signal. A high voltage current detection circuit characterized in that a voltage signal corresponding to the output current of the power amplifier is obtained.
