Date Jan. 30, 1997A switched-mode power supply with a transformer where the output current or the output voltage is controlled or regulated as a function of the, magnetic flux density of the transformer. Thus it is advantageously avoided that the transformer runs into saturation, especially at large pulse widths. Due to the fact that the magnetic flux density is limited to a preset level, the power components can be optimized because of the limited thermal stress.
