Abstract
An electrosurgical generator for generating a high-frequency AC voltage for an electrosurgical instrument, having a high-voltage inverter that generates and outputs a high-frequency AC voltage. A filter having a parallel capacitor is on an output line. A measuring sensor circuit having a current divider, which has a capacitive coupling to a series-connected shunt as bypass with respect to the parallel capacitor, and having a voltage detection circuit connected to the shunt. The shunt has a considerably lower impedance than the capacitive coupling. This gives rise to a proportional ratio between the current flowing through the parallel capacitor on the output line of the electrosurgical generator and the current through the shunt. This current is converted into a voltage, which is detected. The current at the output of the inverter is determined quickly and accurately thanks to the proportional relationship. This may be used for feedback and improved monitoring and regulation.
