ABSTRACT:
A switched-mode power supply with sinusoidal current consumption includes a rectifier receiving a sinusoidal alternating voltage and having an output at which a rectified alternating voltage can be picked up. A switched controller receives the rectified alternating voltage as an input signal and supplies an output signal. A multiplier device receives and multiplies the input signal by the output signal of the switched controller and generates an output signal being supplied to the switched controller. A divider divides the output signal of the switched controller being supplied to the multiplier device by the input signal being supplied to the controller and weighted on a basis of a transfer function formed by at least two linear partial functions, and delivers a resultant signal to the multiplier device.
