ABSTRACT:
A circuit arrangement for interruptionless switching to the higher of two feed voltages in a buffered current supply. Each of the feed voltages is applied to the base of a driving transistor, via a diode, and to the emitter of a complementary switching transistor. The emitters of both driving transistors are connected to reference potential via a common resistor. The collector of each driving transistor is connected to the base of the respective switching transistor and the collectors of both switching transistors are connected to the output terminal. Switching to the higher of the two applied voltages is automatic and instantaneous.
