摘要： A system and method for return electrode monitoring are provided. The system includes an isolation circuit, a first controller, a second controller, and a detection circuit. The isolation circuit includes a transformer having a primary winding and a secondary winding. The first controller is coupled to the primary winding. The second controller and the detection circuit are coupled to the secondary winding. The detection circuit includes an interrogation signal circuit, a resonant tank filter, and a current-to-voltage converter. The interrogation signal circuit provides an interrogation signal to at least one electrode pad. The resonant tank filter filters a response signal received from the electrode pad. The current-to-voltage converter generates a voltage signal based on a current value of the response signal. The second controller generates a digital impedance value based on the voltage signal, and provides the digital impedance value to the first controller by way of the isolation circuit.

摘要： The electrosurgical systems and methods of the present disclosure monitor power dosage delivered to tissue being treated with improved speed and accuracy. The electrosurgical systems include an output stage, sensors, analog all-pass filters, an analog multiplier, an average power calculation circuit, and a controller. The output stage generates electrosurgical energy to treat tissue. The plurality of sensors sense voltage and current waveforms of the generated electrosurgical energy. The plurality of analog all-pass filters filter the sensed voltage and current waveforms. The plurality of analog all-pass filter may have lagging or leading phase. The analog multiplier multiplies the filtered voltage and current waveforms to obtain a real power waveform. The average power calculation circuit calculates a real average power based on the real power waveform. The controller then generates a control signal to control the output stage based on the real average power.
