| description | An electrosurgical generator and related systems and methods using a gain-compensated full bridge topology. Gain nonlinearity is corrected by applying impedance and phase correction factors to a control loop to achieve a linear gain structure. In embodiments, gain compensation is performed by comparing an RF setpoint signal with a calculated output signal to generate a first error signal. An impedance correction factor is applied to the first error signal to generate a second error signal. The second error signal is processed by a proportional-integral-derivative controller to generate a phase control signal. A phase control correction factor is applied to the phase control signal to generate a corrected pulse width modulation driving signal, which is used to generate PWM driving signals for a full-bridge inverter. One or more sensors provide feedback for comparison with the RF setpoint. |
