摘要:
The disclosed embodiments relate to power systems and methods. One such power system includes an adapter that produces a power output. A converter stage receives the power output and in turn provides a regulated output. The regulated output is delivered to a battery and to a DC-DC component.

One embodiment is a computer that includes a controller and a battery with a fuel gauge. The fuel gauge reports voltage and current input to charge the battery while the computer is in an off-state. The controller receives information about the voltage and current input to charge the battery from the fuel gauge and uses the information to calculate power being input to the computer while the computer is in an on-state.

A sealed rechargeable lithium-ion battery pack which includes a switching voltage regulator. The regulator uses the normal cutoff transistors as the switching devices, and also includes a discrete inductor in the battery pack. The regulator is operated with programmable voltage and current parameters, under control of a microcontroller which is also inside the sealed battery pack enclosure.

An integration ring is configured to interconnect two components, such as an exhaust manifold and a turbine housing. The integration ring may include an outer wall and an inner wall spaced apart from one another. A spacer may be positioned between the inner wall and outer wall. A first and second pocket may be formed between the inner and outer walls.

In one embodiment, a power adapter comprises a power supply to output power for powering a powered device. The power adapter outputs information indicative of an amount of power output by the power supply for use by the powered device to control the amount of power used by the powered device.
摘要:
A constant voltage/constant power AC adapter converts AC voltage to DC voltage to provide power to a plurality of loads. The adapter's output characteristic is approximately a constant voltage as long as the output current draw by the loads is less than a threshold (e.g., a safety threshold for the adapter). If, however, the power draw on the adapter is such that the output current exceeds the threshold, the adapter then decreases its output voltage to maintain the power draw at a safe level. One or more loads that draw power from the adapter may be adapted to detect a drop in the AC adapter's output voltage. When such a voltage drop is detected, that information tells the load that too much current is being drawn from the adapter and that the load should throttle back (e.g., reducing battery charge current, CPU clock frequency, display brightness, etc.).

In at least some embodiments, a power converter comprises control logic adapted to be mounted on a first circuit board and a power component adapted to be electrically coupled to the control logic and adapted to be mounted on a second circuit board. The first circuit board mechanically attaches to the second circuit board. In other embodiments, a system comprises a system board, a module attached to the system board, and a power converter comprising a controller electrically coupled to a power component. The controller is mounted on the module and the power component is mounted on the system board.
摘要:
In at least some embodiments, a system comprises a load and a fuel cell coupled to said load, the fuel cell being configured to provide a constant power level to said load. The system further comprises a battery coupled to said load and configured to provide power in excess of said constant power level to said load, if needed by said load.
