Abstract

Viene descritto un filtro per l'attenuazione dei disturbi a radiofrequenza prodotti da un dispositivo di regolazione dell'alimentazione di un carico mediante un triac (TR1) che può essere utilizzato indifferentemente in applicazioni con carico resistivo e con carico induttivo. Esso presenta, oltre agli usuali componenti di un filtro adatto solo per carichi resistivi (L1, C1, C2, R1), un condensatore (C3) ed un resistore (R2) collegati, in serie tra loro, tra i terminali di potenza (5, 7) del triac (TR1).
