Abstract
A power converter with an adjustable output voltage has an isolation DC/DC transformer, a primary side circuit connected to a primary coil of the isolation DC/DC transformer for transmitting an input AC power to the primary coil, and a secondary side circuit connected to a secondary coil of the isolation DC/DC transformer. The secondary side circuit includes a first output loop, a second output loop and a mode switch connected in the first output loop. When power consumption of a load is low, the mode switch is turned off to interrupt the first output loop so that the secondary side circuit generates a first output voltage with a low voltage level. When power consumption of a load is high, the mode switch is turned on and the secondary side circuit generates a second output voltage with a high voltage level. Without greatly increasing circuits, the power converter achieves wide-range voltage regulation.
