    Abstract: An impedance monitoring circuit for an electrosurgical generator is disclosed. The monitoring circuit includes an isolation transformer coupled to at least one of an active terminal and a return terminal of an electrosurgical generator, wherein the isolation transformer includes a primary winding coupled to a reference resistor and a secondary winding coupled to a load. The monitoring circuit also includes a driver configured to transmit a sensor signal to the reference resistor and the load, a primary converter coupled to the reference resistor and the load and configured to detect a primary converted signal as a function of the sensor signal passing through the reference resistor and the load. The monitoring circuit further includes a secondary converter coupled to the driver and configured to detect a secondary converted signal as a function of the sensor signal prior to passing through the reference resistor and the load and a controller configured to determine a fault condition based on the primary and secondary converted signals.

    Abstract: An electrosurgical system and method are disclosed. The system includes an electrosurgical generator adapted to supply electrosurgical energy to tissue. The generator is further adapted to supply an electrosurgical signal at a variable power level. The generator includes sensor circuitry adapted to sense tissue impedance and/or an electrosurgical signal zero crossing. The generator also includes a controller, which may include a microprocessor, that is adapted to receive a tissue impedance signal and/or a waveform zero crossing signal. The controller is configured to monitor tissue impedance, and in response to a threshold value of impedance being reached, to cause a power level of the electrosurgical energy to transition from a first power level to a second power level. The slew rate of the power transition may be in accordance with a transition function, such as a cosine function. The power transition may additionally or alternatively be performed during, or correlated with, an electrosurgical signal zero crossing. The system also includes an electrosurgical instrument including at least one active electrode adapted to apply electrosurgical energy to tissue for treatment.
