METHOD AND DEVICE FOR SUPPLYING AN ELECTRIC CONSUMER WITH A REGULATED ELECTRIC VOLTAGE OR CURRENT

摘要

Electromagnetic radiation (R) of a transmitted (3) is converted by a receiver (4) to an electric power supply voltage (U) for an electric consumer (2). The power supply voltage (U) is controlled at a reference value (REF) by controlling the transmitting power of the transmitter (3). Thus aging phenomena in transmitter (3) and receiver (4) and changes in attenuation in the transmission link can be compensated. The radiation (R) is preferably light from a wavelength range between 400 nm and 1400 nm.
