ABSTRACT:
An arrangement for the inductive querying of and supplying of power to an isolated circuit having an electrical consuming device. The arrangement uses two isolating transformers each with a read winding to simultaneously compare the resistance of the consuming device with that of a simulation device when powered by a low alternating test current. Te arrangement has two outputs for test voltages corresponding to resistance deviations of the consuming device and the reference element, deviate in opposite directions. A bidirectional crosswise transmission of the testing power and the testing signal for the consuming device and the simulation compensates for tolerances of the transformers. When an increased alternating current is fed, the arrangement also causes the efficient supplying of power to the consuming device and a limiting of the power loss at the simulation. A CAN/VAN integratable arrangement performs the testing of and supplying of power to the triggering circuit of a safety system, as well as the inductive supplying of power to a steering wheel computer and the cableless command transmission, for example, for the actuating of signal devices.
