  • Patent number: 12046896
    Abstract: A power supply comprises a DC power source, first and second DC/DC converters, and a protection circuit. The DC power source provides DC power at a variable bulk voltage. The first DC/DC converter converts the DC power from the DC power source to DC power at a high voltage suitable for powering a high-voltage load. The second DC/DC converter receives DC power from the first DC/DC converter, converts the received DC power to DC power at a low voltage, and delivers the DC power at the low voltage to a low-voltage load. The protection circuit selectively transfers DC power from the first DC/DC converter to the high-voltage load. The DC power source may be an AC/DC converter receiving AC power from a power generator driven by an aircraft engine.

  • Patent number: 12036893
    Abstract: A power supply system includes a power conversion circuit that is connectable to a power storage unit. The power supply system includes a control unit and a heat transferring unit. The control unit supplies a current between the power storage unit and the power conversion circuit by performing on-off control of a switch that configures the power conversion circuit. The heat transferring unit absorbs heat that is generated in the power conversion circuit in accompaniment with the on-off control of the switch and transfers the heat to a temperature-increase target element. The control unit performs temperature-increase mode control in which the switch is on-off controlled such that an amount of heat that is generated in the power conversion circuit is increased when a temperature-increase request for the temperature-increase target element is present, compared to when the temperature-increase request is not present.
