Current detection device for pulse width modulated electronic setting elements e.g. for drive regulator, uses control device for switching gate unit with 2 transistors for measuring current at discrete intervals

摘要

The current detection device has a control device for switching a gate unit with 2 transistors (T1,T2) for measurement of the current at discrete time intervals via a measuring resistance (Rm) coupled to a measuring device (ME) containing a measuring amplifier (MV). The measuring resistance is connected in series with the output of the bridge circuit provided by the transistors, or is connected in the positive or negative supply line for the bridge circuit.
