Device for combined transmission of energy and electric signals

Abstract

A device in the form of a transformer for transmitting electrical energy is comprised of a core of a ferromagnetic material and a primary coil and a secondary coil wound about the core. At least one receiver in the form of an areal antenna and at least one sender in the form an areal antenna are arranged in the direct vicinity of the primary and secondary coils for a contact-free transmittal of changing signals. The receiver and the sender are connected interchangeably to receiving and sending electronics devices, whereby the receiver and the sender form a constructive unit with the primary coil, the secondary coil, and optionally the core. The device allows the simultaneous transmittal of electric energy between components that are adjustable relative to one another as well as the transmittal of changing signals. The power transmittal in the kilowatt range is only limited by the respective constructive size of the device. A high data transmittal rate of analog or digital changing signals is possible.
