Abstract
An interface method and system for interfacing a DC unbalanced databus with a DC balanced databus suited for use in an aircraft. The system includes a DC unbalanced databus and a controller coupled to the DC unbalanced databus. An alternating DC unbalanced voltage differential signal is transmittable from the controller to a first transformer which is coupled to the controller. The alternating DC unbalanced voltage differential signal may be stepped-up and DC balanced by the first transformer to create a DC balanced voltage differential signal. A transmitter is coupled to the first transformer, where the transmitter comprises a high power differential voltage driver. The DC balanced voltage differential signal may be stepped up by the transmitter to a high drive current signal. A second transformer is coupled to the transmitter, and at least one DC balanced databus is coupled to the second transformer. A waveform shaping network may be coupled between the second transformer and DC balanced databus. A receiver may be coupled to the transmitter, second transformer, and controller. Advantages include providing a cost-effective HIRF-resistant databus where signals are transmittable for up to 300 feet.
