This paper presents a fully-digital-controlled shunt active filter for harmonic termination of a power distribution system. The main purpose of the active filter based on voltage detection is not to compensate for current harmonics but to damp

Passive filter and active filter are two ahnative strategi- es to suppress harmonics in the electrical distribution system. Pas- sive filter is dc and efficient but it may cause the resonimce problem. Active film has become a mature tecblogy
