POWER ADAPTER WITH LOW POWER LOSS
First Claim
1. A power adapter, connected between a power source and a powered device comprising a jack comprising a magnetic element, the power adapter comprising:
- a power converter circuit, operable to convert power signals of the power source into direct current (DC) power signals suitable for driving the powered device;
a DC plug connected to the power converter circuit and engageable with the jack of the powered device, operable to transmit the DC power signals to the powered device, the DC plug comprising a magnetic force conducting wire to conduct magnetic force of the magnetic element when the powered device is powered; and
a magnetic switch connected between the power source and the power converter circuit, operable to be turned on or off according to if the magnetic force conducting wire conducts the magnetic force or not, so as to control the power source to provide power to the power converter circuit.

Abstract
A power adapter includes a power converter circuit, a direct current (DC) plug and a magnetic switch. The power converter circuit converts power signals of a power source into DC power signals. The DC plug is engageable with a jack of a powered device, and transmits the DC power signals to the powered device. The DC plug includes a magnetic force conducting wire to conduct magnetic force of a magnetic element when the powered device is powered. The magnetic switch, connected between the power source and the power converter circuit, is turned on or off according to if the magnetic force conducting wire conducts the magnetic force or not so as to control the power source to provide power to the power converter circuit.
