The operating voltage required by each part is generated. The operating voltage generated in the constant voltage circuit is provided to the input circuit, the output circuit and the control circuit.

The current detector 140 detects a current amount of the commercial AC power supplied through the AC power input terminal, and supplies the commercial AC power of the AC power input terminal to the third connector 13 designated as the main outlet. The current detector 140 may be implemented by a general transformer. When the computer main body 1 is in use, an amount of current of a predetermined magnitude is detected, and when not in use, an amount of current close to zero (of course, not a small zero and a slight minute current flows) is detected. Therefore, the controller 150 may determine whether the computer main body 1 is turned on or off according to the amount of current detected by the current detector 140.

And a connector switching unit connected to the plurality of connector units and controlled by the control unit so that any one of the plurality of connector units may be designated as a main outlet based on the information received from the data transmission / reception unit. Power supply. The method of claim 2,
A computer main body is connected to a connector unit designated as a main outlet by the information received through the data transmitting and receiving unit, and the computer main body is supplied with power from the connector unit by a universal serial bus (USB) communication method, and the data transmitting and receiving unit, And at least one of the current detector and the controller. The method of claim 3,
And an AC-DC converter unit for converting AC power into DC power while the switching unit is turned on to supply DC power to an external device. The method of claim 4, wherein
The data transceiving unit receives information received from a mobile electronic device in which wireless Internet communication with a wireless Internet modem supplied with DC power from the AC-DC converter and transmits the information to the control unit,
The control unit controls the connector units so that the power supply of all the connector units including the power supply of the connector unit designated as the main outlet or the auxiliary outlet can be cut off or resumed, and the data stored in the computer main body through the data transmission and reception unit. Power supply, characterized in that provided to the electronic device. The method of claim 5,
It further includes a DC power sensor connected to the output line of the AC-DC converter unit and the data transmission and reception unit for detecting a DC power supply state from the AC-DC converter unit to an external device and transferring the detected result to the data transmission and reception unit. Power supply characterized in that. The method according to any one of claims 1 to 6,
Some of the connector units constitute a power saving outlet unit in which the amount of current per hour is detected in real time by the current detection unit and controlled on / off by the control unit, and another portion of the connector units steadily supplies constant AC power. Power supply, characterized in that the configuration of the unit. The method of claim 7, wherein
And an auxiliary switching unit provided to block or resume power supply of at least one of the power saving outlet unit and the general outlet unit. A control method for a power supply apparatus having a plurality of connector parts to which a plurality of electronic devices are connected, respectively, so that power can be supplied to the plurality of electronic devices.
The step of collectively interrupting or resuming the supply of AC power by the switching unit;
Receiving information from the outside through a data transmission / reception unit such that any one of the plurality of connector units is arbitrarily designated as a main outlet while the switching unit is turned on;
Detecting, by the current detector, a power supply state to the electronic device through the connector portion designated as the main outlet and a change value of the current per hour;
On the basis of the information detected by the current detector, if it is determined that there is no power supply to the electronic device through the connector portion designated as the main outlet, the power supply through the connector portions, which are remaining auxiliary outlets, is also cut off, and through the connector portion designated as the main outlet If the power supply to the electronic device is judged to be resumed, the power supply through the remaining connector outlets is resumed. If the change in the hourly current to the electronic device through the connector unit designated as the main outlet is rapidly increased, all the connectors When the power supply through the parts is cut off and the change in the hourly current to the electronic device through the connector part designated as the main outlet is rapidly reduced, the control unit controls the connector parts so that only the power supply through the remaining connector outlets is cut off. To control each Control method for a power supply comprising a. 10. The method of claim 9,
Any one of the plurality of connector parts may be designated as a main outlet based on information received from the data transceiver between the step of receiving information from the outside through the data transceiver and the current detection by the current detector. The control method for a power supply characterized in that the control unit further comprises the step of controlling the connector switching unit.
