Abstract

Die beschriebene Stromquelle ist eine Stromquelle, die zwischen einem stromgesteuerten Modus und einem spannungsgesteuerten Modus umschaltbar ist. Durch eine besondere Ansteuerung der Stromquelle wird erreicht, daß diese bei nur zwei Eingangsanschlüssen unter allen Umständen ordnungsgemäß und stabil arbeitet.

Figure 00000001
The current source described is a current source that can be switched between a current-controlled mode and a voltage-controlled mode. A special control of the current source ensures that it works properly and stably under all circumstances with only two input connections.
