ACTIVE DISTORTION REDUCTION OF POWER SOURCES

Balázs Vargha, László Sujbert

Abstract

Quality of power sources is mainly increased by using better components and tricky electronic circuits. The paper introduces a control loop, which is similar to that used for the active cancellation of acoustic noise signals. In the feedback loop, the distortions of the signal are estimated by a combination of an adaptive Fourier analyzer and a resonator-based observer. Only the distortions should be compensated, therefore the actuator signal has low power. The paper introduces the active distortion reduction system and presents practical results, as well.
