Abstract
A method and generator for modifying interactions between a load and the generator are described. The method includes applying output power to the load using a power amplifier, controlling a level of the output power responsive to a power control setting, and adjusting a conduction angle of the power amplifier to reduce a level of sensitivity of the power amplifier to variations of an impedance of the load. The generator includes a compensation subsystem coupled to the power amplifier that controls a conduction angle of the power amplifier to enable a sensitivity of the power amplifier to be adjusted.
