Abstract
A power supply has multiple DC power sources converted from an AC power source. The power supply has an isolated converter converting the AC power source into an intermediate DC power source, and non-isolated converters converting the intermediate DC power source into the DC power sources, regulated at target output values respectively. A communication channel connects the isolated converter and one of the non-isolated converters, and transmits a feedback signal in association with the target output values. The isolated converter, in response to the feedback signal, regulates the intermediate DC power source at an intermediate target value related to the target output values.
