Abstract
An electrosurgical unit having power monitoring circuitry for reducing leakage current in an electrosurgical unit. The electrosurgical unit includes a power source configured to produce direct current, an RF waveform generator configured to convert the direct current into an RF signal, a voltage sensor configured to measure DC input voltage to the RF waveform generator, a current sensor configured to measure output current feedback, and a processor. The processor is configured to estimate output voltage feedback based at least upon the measured DC input voltage and the measured output current feedback, and output a control signal to control the DC input voltage to the RF waveform generator, the control signal based at least upon the estimated output voltage and the output current feedback.
