Claim Text:
1. A power supply, comprising: a first switched-mode power-supply circuit including a transformer and a first switching controller, wherein the first switched-mode power-supply circuit is configured to output a first power signal based on a first switching signal from the first switching controller; a second switched-mode power-supply circuit including a second switching controller that is configured to monitor an output voltage of a winding of the transformer, wherein the second switched-mode power-supply circuit is electrically coupled to the first switched-mode power-supply circuit and configured to output a second power signal based on a second switching signal from the second switching controller, wherein the first switching signal and the second switching signal have a common fundamental frequency; and a storage mechanism configured to store information specifying a phase value; wherein the second switching controller is configured to establish a phase shift, corresponding to the phase value, between the first switching signal and the second switching signal based on the stored information and the monitored output voltage of the winding.
