Abstract
A circuit arrangement having an overload protection for galvanic isolation units for galvanic isolation from one another is described. The galvanic isolation units each have two regions galvanically isolated from one another and one of the regions has a control signal terminal and a base terminal. The circuit arrangement have at least two such galvanic isolation units. From at least two of the galvanic isolation units the base terminals of a region are electrically conductively connected to one another and are connected to a base potential via a common fuse connected in series.

A circuit arrangement having an overload protection for galvanic isolation units for galvanic isolation from one another, wherein the galvanic isolation units each have two regions galvanically isolated from one another and one of the regions has a control signal terminal and a base terminal, wherein the circuit arrangement has at least two such galvanic isolation units, wherein from at least two of the galvanic isolation units the base terminals of a region are electrically conductively connected to one another and are connected to a base potential via a common fuse connected in series and the control signal terminals of the galvanic isolation units are connected directly or indirectly in each case to an assigned control signal terminal of a control unit.
A circuit arrangement having an overload protection for galvanic isolation units for galvanic isolation from one another, comprising:
- at least two galvanic isolation units each having two regions galvanically isolated from one another, one of the two regions having a control signal terminal and a base terminal,
- wherein the base terminal for each of the at least two galvanic isolation units is electrically conductively connected to one another at a first node, the first node maintained at a base potential via a common fuse electrically connected between the first node and the base potential.
