Bordnetzversorgung bei Busankoppler ohne Übertrager |
摘要 |
A device for establishing the on-board power supply in a bus coupler without a repeater for coupling to an information and power conducting bus (bus driver 1, 2) of a bus system, especially in the building management. The control input (4) of a coupling circuit (3) is connected to a triggering circuit (5) having inputs (6, 7) for a control criterion. The coupling circuit (3) is constructed and designed in such a way that it operates as a constant current source for communication frequencies and as a control circuit together with a triggering circuit (5) for lower frequencies, like those caused by power consumption. The coupling circuit (3) is connected depending on the effect in series with a storage capacitor (8) to tap the on-board system voltage. The series circuit is, according to the effect, connected to the bus drivers (1, 2).
