Circuit for switchable load control-drive

The circuit output stage (AS) consists of two semi-connected, energisable switches (S1, 2). The first switch (S1) is coupled to a voltage source (US1) at first switch terminal (SA1). The second switch is similarly coupled to a voltage source (US2) at second terminal (SA2). At least the first switch...

Zusammenfassung:The circuit output stage (AS) consists of two semi-connected, energisable switches (S1, 2). The first switch (S1) is coupled to a voltage source (US1) at first switch terminal (SA1). The second switch is similarly coupled to a voltage source (US2) at second terminal (SA2). At least the first switch has several semi-connected bipolar switching elements (SE1, SE1'). such element has at least three terminals, one as a control terminal. The first switch has several energising elements (T5, 6) for energising the bipolar switching elements, with one energising element coupled to the control terminal of one switching element. The second switch terminals of both switches are coupled to a common output terminal (A).
