  • Publication number: 20220133391
    Abstract: An electrosurgical generator includes a power supply unit which, when operating, supplies a direct voltage circuit, and a high-voltage inverter supplied from it that generates a high-frequency alternating voltage that is applied to outputs for connection of the electrosurgical instrument. The inverter includes a clock-driven power switch and a zero-crossing detector that recognizes zero crossings of the oscillation generated by the inverter. A signal for the generated alternating voltage is applied to the zero-crossing detector via a voltage divider which is a capacitive voltage divider with at least one capacitor that is resistant to high voltage. Undesirable direct voltage components at the center tap in the presence of changes to the supply voltage can be avoided thereby, since charge reversals as a result of changes to the supply voltage occur on both sides, and their effects thus cancel out.
