Abstract: The invention provides a device for stabilizing an effective value of an output current of a converter. The device comprises the following: an input to receive an input voltage x of the converter, a memory in which a first set of polynomial coefficients a, b, c; kj is stored, a processor that is coupled to the input and the memory and is set up so as to determine a current correction y as a polynomial function with the stored first set of polynomial coefficients a, b, c; kj as a function of the received input voltage x, and a power stage that is coupled to the processor to receive the current correction y and set up to modify the effective value of the output current as a function of the current correction y.

Abstract: A DC power supply (1) having a series regulator (2) for generating a fixed output DC voltage (VCC) at a variable input AC voltage (VAC) with low power loss. For this purpose, the DC power supply (1, 101, 201, 301) has a transformer (3, 103) having at least two auxiliary windings (W1, W2) having different numbers of windings that can each be connected via a switching device (4, 104, 204, 304) to the series regulator (2). Switching is effected such that the power loss is kept as low as possible.
