Abstract
A power supply includes a storage capacitor which can be charged with a rectified input current by means of a current-limiting element which is controlled by a drive circuit. The direct-axis component of current and the direct-axis component of voltage on the current limiting element are supplied to the control circuit as input values and the current limiting element is controlled in such a way that it is not subjected to more than a predetermined maximum power loss.
