Abstract

Il circuito comprende n rami circuitali (B1, B2, B3) in ciascuno dei quali un commutatore elettronico di potenza (M1, M2, M3) è in serie ad un avvolgimento o fase (W1, W2, W3) del motore, fra i terminali di una sorgente di tensione (Vs). Alle fasi (W1, W2, W3) del motore sono connessi dispositivi di ricircolo (Q1, R21, D11, M1,...) per smaltire la corrente transitoria che circola in ciascuna fase ogni volta che l'associato commutatore elettronico (M1, M2, M3) viene disabilitato. Dispositivi limitatori di tensione (D1, R11, ecc.; C) limitano la sovratensione (Vp1, Vp2, Vp3) che si sviluppa su ciascuna fase (W1, W2, W3) per effetto di detta corrente transitoria ad un valore di soglia (Vth) variabile secondo una funzione crescente della velocità del motore.(Figura 1).
