Abstract

A power supply with performance display is disclosed. The computer power supply mainly has a power converter, a control module, and a display. The control module receives and processes the operating signals from the power converter, and then sends those processed signals to a display in a numerical value form. The power supply can be applied in a computer, an adapter, or other electronic products, which is convenient for users to know the operating status of the power converter.

Claims

1. A power supply with performance display comprising:

a power converter to transform external power to at least one direct current power;

a control module comprising at least a microprocessor and an analog to digital (A/D) converter, wherein the microprocessor is connected to the power converter through the A/D converter, to get signals from the power converter; and

a display connected with the control module.

2. The power supply with performance display as claimed in claim 1 wherein the A/D converter in the control module is connected with the power converter (10) to receive status signals from the power converter.

3. The power supply with performance display as claimed in claim 2 wherein the status signals include at least one voltage signal representing an output current of the power converter.

4. The power supply with performance display as claimed in claim 2, wherein the control module further comprises an external interrupt source that receives a warning signal generated from the power converter, and further informs the microprocessor when the warning signal has a status change.

5. The power supply with performance display as claimed in claim 2, wherein the control module further comprises a real time clock to count a total operation time of the power converter.

6. The power supply with performance display as claimed in claim 2, the power converter further comprising a temperature sensing circuit with an output connected to the A/D converter, wherein temperature signals output from the temperature sensing circuit are processed by the A/D converter and then sent to the microprocessor.

7. The power supply with performance display as claimed in claim 6, wherein the power converter further comprises a cooling fan that outputs a speed signal representing a rotation speed of the cooling fan;

and

the control module further comprises a time/number counter and a digital to analog (D/A) converter both connected to the microprocessor, wherein the speed signal are received by the time/number counter and further transmitted to the microprocessor so that the microprocessor is able to output a control signal in response to the speed signal to adjust the rotation speed of the cooling fan through the D/A converter.

8. The power supply with performance display as claimed in claim 2, wherein the control module further comprises a memory.

9. The power supply with performance display as claimed in claim 2, wherein the control module further comprises a transmission interface for data communicating with a computer through a communication protocol.

10. The power supply with performance display as claimed in claim 9 wherein the microprocessor is linked with a monitoring application program built in an operation system of the computer, and provides an operating window shown on a desktop display connected to the computer.

11. The power supply with performance display as claimed in claim 10, wherein the transmission interface is a serial bus.

12. The power supply with performance display as claimed in claim 7, wherein the control module further comprises a control interface connected with the microprocessor.

13. The power supply with performance display as claimed in claim 12, wherein the control interface has press keys thereon.

14. The power supply with performance display as claimed in claim 6, wherein the control module further comprises an alarm generator connected to the microprocessor.

15. The power supply with performance display as claimed in claim 14, wherein the alarm generator is a buzzer.

16. The power supply with performance display as claimed in claim 8, wherein the memory is an electrically erasable programmable read only memory (EEPROM).

17. The power supply with performance display as claimed in claim 8, wherein the memory is a flash RAM.

18. The power supply with performance display as claimed in claim 1, wherein the display is an LCD.

19. The power supply with performance display as claimed in claim 1, wherein the display is an LED-based display.
