Verfahren und Vorrichtung zur Energierückgewinnung bei der Ansteuerung induktiver Lasten

摘要

A circuit device for recovering energy in inductive load (L) driving, being of a type associated with a driver circuit (2) for the inductive load (L) which is connected to a power supply line (4), comprises: a charge accumulator (C) connected to one end of the inductive load (L); a control circuit (3) monitoring the charge level (V) of the accumulator (C); an on/off switch (S) linked operatively to the control circuit (3) and connecting the accumulator (C) to the power supply line (4); and a switch means (IC1) connected between the accumulator and the inductive load (L) to intermittently discharge the inductive load (L) as the driver circuit (2) is controlled to turn off.
