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.
