  • Patent number: 12166416
    Abstract: A power supply includes a first (main) power converter and a second (auxiliary) power converter disposed in parallel with the first power converter to produce an output voltage to power a dynamic load. The second power converter includes a primary inductive path magnetically coupled to a secondary inductive path. A controller controls a flow of first current through the primary inductive path of the second power converter to control flow of second current supplied by the secondary inductive path to the dynamic load. During steady state conditions, the first power converter produces the output voltage while the second power converter is deactivated. During transient load conditions, the second power converter provides current boost capability to maintain a magnitude of the output voltage within a desired range.
