  • Patent number: 12244173
    Abstract: This disclosure includes novel ways of implementing a power supply that powers a load. More specifically, a power supply includes a bidirectional power converter and a controller. The controller monitors a magnitude of an input voltage supplied from an input voltage source to a load. Based on a magnitude of the input voltage, the controller switches between a first mode of operating the bidirectional power converter to charge an energy storage resource using (a portion of power provided by) the input voltage and a second mode of producing a backup voltage from the energy storage resource to power the load as a substitute to the input voltage such as when the input voltage is below a threshold value.

  • Patent number: 12218597
    Abstract: A power supply includes a controller. The controller controls switching of a first switch and a second switch in a power supply to regulate conveyance of energy from a primary winding of a transformer to a secondary winding of the transformer to generate an output voltage. To control generation of the output voltage, the controller receives a first signal generated at a first node coupling the first switch and the second switch. As discussed herein, the controller controls activation of the first switch to an ON state depending on a magnitude of the first signal. This disclosure provides improved reliability of power supply components (such as one or more switches) because such components are no longer stressed (or overstressed) due to body diode cross conduction.
