摘要： Certain aspects of the present disclosure provide an apparatus comprising a battery encapsulated within a sealed enclosure, an electronic device encapsulated within the sealed enclosure, a power control circuit encapsulated within the sealed enclosure, and a loop of conductive medium connected to the power control circuit. The electronic device is in a deactivated state. At least a portion of the loop of conductive medium passes out of and back into the sealed enclosure. In response to severing of the at least portion of the loop of conductive medium which is outside of the sealed enclosure, the power control circuit is configured to cause activation of the electronic device.

摘要： The present invention discloses a power supply circuit and a UPS auxiliary power supply system having the same. The power supply circuit comprises a transformer, a primary-side switch unit and a secondary-side switch unit. When the input power supply is powered on, the second switch of the secondary-side switch unit maintains in an off state, the first switch of the primary-side switch unit performs an on-off action, and the input power supply supplies power to the load and the energy storage unit. When the input power supply is powered down, the first switch of the primary-side switch unit maintains in an off state, the second switch of the secondary-side switch unit performs an on-off action, and the energy storage unit supplies power to the load.

摘要： A power generating apparatus includes a power supply, a first sub-end circuit, a second sub-end circuit and an integrated signal generator. The first and second sub-end circuits respectively generate first and second sub-end standby power. The first sub-end circuit receives a first integrated control signal. The second sub-end circuit receives a second integrated control signal. The first sub-end circuit cuts off the first sub-end standby power according to the first integrated control signal and turns on the first sub-end standby power again after a first delay time. The second sub-end circuit cuts off the second sub-end standby power according to the second integrated control signal, and turns on the second sub-end standby power again after a second delay time. The integrated signal generator generates the first and second integrated control signals.

摘要： A first controller for a first DC/DC converter is configured to generate a first current command value based on a smallest value of an output current when an output voltage of the solar battery is equal to an optimum operating voltage in maximum power point tracking control and an output current for outputting a consumption current between the solar battery and the DC load and a charging current of the power storage apparatus. A second controller for a second DC/DC converter is configured to generate a second current command value such that a voltage of the output terminal is equal to a reference voltage.

摘要： A request is received for a higher torque from a torque controller than is possible from a power supply. The torque controller is coupled to a motor and the power supply, and the motor is coupled to an actuator. The actuator ultimately establishes resistance for a user in an exercise. An energy storage device is discharged to the motor in order to generate the higher torque, wherein the energy storage device is indirectly coupled to the torque controller.

摘要： In general, one or more loads on a vehicle can be connected to both a first voltage source on the vehicle and a backup vehicle power system on the vehicle. If the voltage provided by the first voltage source to the one or more loads satisfies a voltage threshold, the backup vehicle power system does not provide power to the one or more loads. However, if the voltage provided by the first voltage source to the one or more loads falls below the voltage threshold, the backup vehicle power system provides power to the one or more loads.

摘要： A system includes a direct current uninterruptible power supply (DC UPS) that receives an alternating current (AC) power input and provides a first DC power output. The system also includes a power distribution unit (PDU). The PDU receives the first DC power output from the DC UPS. The PDU converts the first DC power output into a second DC power output that supplies power to at least one component of information technology equipment (ITE) via a DC mating connector.
