ACTIVE HARMONIC FILTER

    ACTIVE HARMONIC FILTER

    1. Introduction

    The active filter enables:
    • Reduction of the harmonic current content
    • Compensation of reactive power
    • Load balancing
    The ac mains current, disturbed by a non-linear load, is measured by the active Filter either directly or indirectly via external current transformers. The harmonic content and reactive power components are detected and processed in a digital control structure.
    The active filter continually generates a compensating current that compensates the harmonic content and reactive current in the load, so the ac mains only has to provide only the active fundamental phase current.
