ABSTRACT:
A method and apparatus for modifying interactions between an electrical generator and a nonlinear load is described. One illustrative embodiment receives a main control signal at a control input of an engine of the electrical generator, the main control signal controlling at least one of output power, output current, and output voltage delivered by the electrical generator to the nonlinear load, the engine being one of a power amplifier and a converter; measures the impedance of the nonlinear load; and feeds to the electrical generator a compensation signal corresponding to the measured impedance, the compensation signal rendering a transfer function of the output power of the electrical generator with respect to the main control signal substantially insensitive to variations in the impedance of the nonlinear load to stabilize the output power of the electrical generator.
