schaltungsanordnung for measuring a vibrant gleichstroms

摘要

A circuit device is proposed for measuring a pulsed D.C. current, in particular a current supplying a D.C. motor, having a shunt connected in the circuit and having a smoothing circuit with a RC unit. The smoothing capacitor (16) of the RC unit (16, 17) is connected on one side via the smoothing resistor (17) to the shunt (15) in the current path (12, 13) to be monitored and, on the other side, to the positive pole (+) of the D.C. source (11).
