Abstract

A device, system and method for a backup power supply are disclosed herein. The backup power supply may use at least one ultra capacitor to store a voltage. The backup power supply may also have a multiphase boost converter to provide a relatively constant voltage from the stored voltage and a constant changing power filter to regulate a current that is used to charge the ultra capacitor. A charging and discharging controller may be used to monitor the status of a power supply and control the charging and discharging of the ultra capacitors.

Claims

1. A backup power supply comprising:

one or more capacitors for storing a voltage;

a multiphase boost converter for providing a relatively constant voltage from the stored voltage of the one or more capacitors;

a constant changing power filter for regulating a current that is used to charge the one or more capacitors; and

a charging and discharging controller for monitoring a status of a power supply and regulating the charging and discharging of the one or more capacitors.

2. The power supply of claim 1, wherein each capacitor is rated for between about 3 to 10 volts.

3. The power supply of claim 1, wherein the multiphase boost converter is a buck boost converter.

4. The power supply of claim 1, wherein the backup power supply is for an ATX computer power supply.

5. The power supply of claim 1, wherein the one or more capacitors are charging during normal operation of a device being supplied power.

6. The power supply of claim 1, wherein the charging and discharging controller signals a device being supplied power when a switch between charging and discharging occurs.

7. The power supply of claim 1, wherein the charging and discharging controller shuts off the voltage supplied by the one or more capacitors when the voltage supplied by the one or more capacitors drops below a predetermine voltage.

8. A backup power supply for a computer power supply comprising:

at least one ultra capacitor for storing a voltage from a AC power source and supplying a DC power supply for a computer;

a multiphase boost converter for providing a constant voltage from the stored voltage;

a constant changing power filter for regulating a current that is used to charge the ultra capacitor; and

a charging and discharging controller for monitoring a status of a power supply, maintaining the at least one ultra capacitor in a charged state during a normal operation period, and draining the at least one ultra capacitor during a backup operation period.

9. The backup power supply of claim 8, wherein each capacitor is rated for between about 3 to 10 volts.

10. The backup power supply of claim 8, wherein the multiphase boost converter is a buck boost converter.

11. The backup power supply of claim 8, wherein the backup power supply is housed within an ATX computer power supply.

12. The backup power supply of claim 8, wherein the one or more capacitors are charging during normal operation a device being supplied power.

13. The backup power supply of claim 8, wherein the charging and discharging controller signals the computer being supplied power when a switch between charging and discharging occurs.

14. The backup power supply of claim 8, wherein the charging and discharging controller shuts off the voltage supplied by the one or more capacitors when the voltage supplied by the one or more capacitors drops below a predetermine voltage.

15. A method for supplying backup power comprising the actions of:

regulating a current of an AC power source to provide a constant current;

charging one or more ultra capacitors from the AC power source with the constant current;

monitoring the status of the AC power source;

discharging the one or more ultra capacitors when the AC power source is disrupted; and

supplying power with a constant voltage to a device via a multiphase boost converter using the discharge of the one or more ultra capacitor.

16. The method for supplying backup power of claim 15, wherein each ultra capacitors is rated for between about 3 to 10 volts.

17. The method for supplying backup power of claim 15, wherein the multiphase boost converter is a buck boost converter.

18. The method for supplying backup power of claim 15, wherein the device is a computer.

19. The method for supplying backup power of claim 15, further comprising the actions of:

signaling the device being supplied power when a switch between charging and discharging the one or more ultra capacitors occurs.

20. The method for supplying backup power of claim 15, further comprising the actions of:

shutting-off the one or more capacitors when a voltage supplied during discharging the one or more ultra capacitors drops below a predetermine voltage.
