EFFICIENT ACTIVE SOURCE IMPEDANCE MODIFICATION OF A POWER AMPLIFIER

摘要

A system, method, and apparatus for stabilizing interactions between an electrical generator and a nonlinear load are described. One illustrative embodiment includes an impedance element that is coupled to an output of the generator and a power source coupled to the impedance element. The power source applies power to, or across, the impedance element so as to reduce energy loss that would ordinarily occur due to energy dissipation by way of the impedance element. In many variations, the power source operates within a defined bandwidth so that a stabilizing effect is achieved outside of this bandwidth.
