Abstract

A built-in type power integrated controller which stably supplies electrical power to a computer system and protects the system from various power failures which may occur in a power supply and a method therefor are provided. The power integrated controller includes a power generator that drops DC voltage generated by a first rectifier in the event of a normal power supply and by a battery in the event of a power outage to DC voltage levels that are supplied to each component of the system and inverts the DC power to AC power. Thus, the size of an inverter decreases so that it is easier to incorporate the inverter into the system. The built-in battery is employed to automatically shut down and boot the system in a case where there is a power failure while a user is away from the system. Furthermore, a power failure status is sent to a system manager and a user working at a remote location through a wired or wireless network thereby enabling them to appropriately cope with the power failure.

Claims

1. A power integrated controller comprising:

a power sensor that senses the status of AC power input from the outside of the power integrated controller and generates a power supply and a power failure signal;

a first rectifier that converts the AC power received through the power sensor to DC power when a power switch is on;

a second rectifier that converts the AC power from the outside into DC power;

a battery that is charged with the DC power converted by the second rectifier in the event of normal power supply and discharges the charged DC power in the event of a power failure;

a power generator that drops the DC power generated by the first rectifier in the event of normal power supply and by the battery in the event of a power failure to DC voltage levels which are supplied to each component of a system, and inverts the DC power to AC power, and

a power operator that, upon receiving a power failure signal from the power sensor, sends information about power failure conditions and battery back-up time to a terminal through a communication network to save work data and issue a shut down command, and upon receiving a power recovery from the power sensor, boots the system and sends a booting message to the terminal through a communication network.

2. The power integrated controller of claim 1, further comprising:

a DC-to-DC converter that drops the DC voltage output from one of the first rectifier and the battery to a plurality of DC voltage levels; and

an inverter that inverts some of the DC power output from one of the first rectifier and the battery to AC power.

3. The power integrated controller of claim 1, further comprising a power protector that cuts off factors which cause voltage fluctuations introduced into the input AC power.

4. The power integrated controller of claim 1, wherein the battery includes an expansion port for connection to another rechargeable battery.

5. The power integrated controller of claim 1, further comprising a booster that boosts the DC power generated by the battery to the same level as a voltage level output from the first rectifier.

6. The power integrated controller of claim 1, further comprising a battery sensor that detects battery back-up time information from a voltage value output from the battery.

7. The power integrated controller of claim 1, wherein the system is automatically turned off after the system is idle for an amount time set by the power operator.

8. A power integrated control method comprising the steps of

upon supplying power to a system, charging a battery and operating the system normally;

operating the battery and sending information about a power failure status and battery back-up time to a system manager and a terminal through a communication network to save work data and shut down the system, upon receipt of a power failure signal; and

booting and logging into the system and sending a booting message to the terminal through a communication network upon receipt of a power recovery signal.

9. The power integrated control method of claim 8, further comprising the step of automatically saving data and shutting down a procedure unless an external command is input after sending information about the power failure status and battery back-up time, and executing the external command if the external command is input.
