Switch regulator for suppressing magnetostrictions has an inductive resistor fed by a primary voltage and wired to a switch charging a capacitor with power from the resistor and a circuit to trigger the switch with a control pulse.

摘要

A primary voltage (12) feeds an inductive resistor (11) wired to a switch (14) that charges a capacitor (15) with power stored in the inductive resistor. A triggering circuit (16) triggers the switch with a control pulse (17). An optocoupler (18) triggered by a control signal (20) derived from a secondary voltage (22) in the capacitor by means of a control unit (24) uses an output control signal (26) to control the triggering circuit. An Independent claim is also included for a method for suppressing magnetostrictions in a switch regulator triggered by a regulating/control pulse.
