At least one comparator ( 110) is configured to provide an error signal to the pulse modulator (115) based on a comparison between an output signal generated by the power supply (27) and a feedback signal generated in response to the application of energy to tissue. A discharge circuit (145) is configured to control discharge of the output of the 10 power supply (27) to an inductive load (150) disposed in parallel with the output of the power supply (27) based on the comparison between the output signal and the feedback signal. The discharge circuit (145) provides a rapid response and time rate control of the delivered electrosurgical energy by controlling the power supply (27) and delivered RF energy in real time, based on a feedback signal generated in response to the application of 15 energy to tissue.
