Zusammenfassung:	AC to DC power supplies are disclosed. One AC to DC power supply includes a transformer having a primary side and a secondary side and a passive rectifier coupled to the secondary side of the transformer. The passive rectifier is configured to rectify AC power at the secondary side to DC power at an output of the rectifier. An active rectifier is configured to control voltages applied to the primary side of the transformer to induce a non-sinusoidal voltage at the secondary side of the transformer and a sinusoidal current drawn by the passive rectifier. An isolating DC-to-DC converter is coupled between the active rectifier and the output of the passive rectifier to magnetically couple power from the active rectifier to the output of the passive rectifier while galvanically isolating the active rectifier from the output of the passive rectifier.
