Abstract
A radio frequency (RF) power generator system includes a power generator that generates a RF power signal that is output to a load. The RF generator generates a forward power feedback signal and a reverse power feedback signal. A controller receives the forward power feedback signal and the reverse power feedback signal. The controller generates a setpoint signal that is output to the power generator. A setpoint modifier receives the forward feedback signal, the reverse feedback signal and an external setpoint signal. The setpoint modifier calculates a forward power limit based on the forward and reverse power feedback signals. The setpoint modifier and outputs a modified setpoint signal to the controller based on one of the forward power limit and the external setpoint signal. The setpoint modifier and the controller can be integrated.
