Circuit pour la commande d'un dispositif magnétostrictif

Circuit for driving magnetostrictive device

Abstract

Provided is a circuit for driving a magnetostrictive device including: a high voltage interrupting circuit section (C 2 ,R 1 ) for interrupting an instantaneously leaking high voltage depending on the switching operation of a power switch (SW); a voltage storage section (C 1 ) for rectifying an input voltage for a half of the positive cycle and storing it; a switching circuit section (Q 1 ) for supplying the voltage stored in the voltage storage section to the magnetostrictive device; and a voltage discharging circuit section (R 5 ) for discharge the voltage remaining in the voltage storage section when the power is interrupted.
