ENERGY SUPPLY DEVICE HAVING TRANSITIONS BETWEEN OPERATION AND STAND-BY THAT ARE DEPENDENT ON THE OUTPUT CURRENT

摘要

The invention relates to an energy supply device (100) for providing an output voltage and an output current, wherein the energy supply device (100) has a first operating state and a second operating state, comprising: a measuring assembly (101) for sensing a current amplitude of the output current of the energy supply device (100); and a signal generator (103) for producing the output voltage and the output current, wherein the signal generator (103) is designed to reduce a voltage amplitude of the output voltage of the energy supply device (100) in the first operating state of the energy supply device (100) in order to switch over to the second operating state if the sensed current amplitude falls below a first current threshold value, and wherein the signal generator (103) is designed to increase a voltage amplitude of the output voltage of the energy supply device (100) in the second operating state of the energy supply device (100) in order to switch over to the first operating state if the sensed current amplitude exceeds a second current threshold value. The invention further relates to a method for operating an energy supply device.
