Abstract
An electronic device may include an alternating current (AC) adapter to receive AC power and to provide a direct current (DC) voltage. The AC adapter may include a transistor and a capacitor. The capacitor to store a voltage based on the received AC power, and the transistor to remove a portion of the power stored in the capacitor based on the received AC power.
Claims29
An electronic device comprising:
- a load;
- a battery port to receive a battery;
- and
- an alternating current (AC) adapter to receive AC power and to provide a direct current (DC) voltage, the AC adapter to include a transistor and a capacitor, the capacitor to store power during a first prescribed time of the received AC power, and the transistor to provide power from the AC adapter during a second prescribed time of the received AC power.

An electronic device comprising:
- a load;
- a port to receive a charge storage device;
- an input port to receive an alternating current (AC) voltage;
- and
- an alternating current (AC) adapter to receive the AC voltage from the input port, the AC adapter to provide a direct current (DC) voltage based on the received AC voltage, the AC adapter to include a capacitor to store a first portion of the AC voltage based at least in part on a value of the received AC voltage, and a second portion of the received AC voltage is to be provided to the charge storage device based at least in part on a value of the received AC voltage.

An electronic device comprising:
- a load;
- a battery port to receive a battery;
- a battery charger to charge the battery;
- a detecting device to determine when a received alternating current (AC) voltage is greater than a prescribed first value, and to determine when the received AC voltage is below a prescribed second value;
- and
- an alternating current (AC) adapter to receive the AC voltage and to provide a direct current (DC) voltage, the AC adapter to include a capacitor to store a voltage based on the determination of the detecting device, and the AC adapter to provide the DC voltage to the battery based on the determination of the detecting device.
