Abstract: Some embodiments provide a DC power distribution system that includes a plurality of DC sources coupled to a plurality of DC buses via respective protection devices that are configured to selectively cause an open-circuit between the DC source and the respective DC bus in the event of a fault or overload condition on the respective DC bus. The plurality of DC buses are coupled to a load combiner, and the system is configured to supply power in parallel from the DC sources via the plurality of DC buses to at least one DC/DC step-down converter via the load combiner, which combines the power supplied via the plurality of DC buses. The DC buses, load combiner, and the DC power sources are configured such that the total maximum load current is capable of being supplied via less than all of the plurality of DC buses in the event that any one of the DC buses is non-operational.

Abstract: A power supply system includes: a first power supply circuit for supplying, to a first load device, DC power output from a first power generation device; and a second power supply circuit for supplying, to a second load device, DC power output from a second power generation device. In a case where the electric power output from the second power generation device is supplied to the first load device, the first power supply circuit and the second power supply circuit are connected to each other after the output voltage of the second power generation device is lowered.

Abstract: A controller of a power supply control is configured to: in response to a failure of a main power supply being detected, execute a fail-safe control in which a connector is interrupted and electric power from a backup power supply is supplied to a second load; in response to a state value indicating a charging state of the backup power supply decreasing to a first threshold during the fail-safe control, execute an advance notice process for giving a user advance notice that a vehicle will be stopped; and in response to the state value decreasing to a second threshold which is smaller than the first threshold and which indicates a safety limit of the backup power supply, execute a power supply stop process for stopping supply of the electric power from the backup power supply.

Abstract: An apparatus comprising a first and second terminals, a sensor, and energy storage device, a plurality of converter, a controller and an auxiliary power circuit. The plurality of power converters are connected to the energy storage device. Each power converter converters power from the energy storage device to the first and second terminals, or from the first and second terminals to the energy storage device. The controller synchronously controls one or more power converters of the plurality of power converters. The auxiliary power circuit provides power to the controller from one or more of a plurality of auxiliary power sources.
