Abstract

An automatic power supply system is electrically coupled to a component to be tested. The automatic power supply system includes a power array and a controller. The power array includes a plurality of power channels, and provides power supplies through the plurality of power channels. The component to be tested is electrically coupled to a first power channel of the plurality of power channels and receives a power supply through the first power channel. The controller is electrically coupled to the power array, and calculates a power of the power supply received by the component to be tested. The controller adjusts a power specification of the power supply provided through the first power channel according to the power.

First claim

What is claimed is:

1. An automatic power supply system electrically coupled to a component to be tested, the automatic power supply system comprising:
a power array comprising a plurality of power channels, and configured to provide power supplies through the plurality of power channels, wherein the component to be tested is electrically coupled to a first power channel of the plurality of power channels and receives a power supply through the first power channel; and
a controller electrically coupled to the power array, and configured to calculate a power of the power supply received by the component to be tested and adjust a power specification of the power supply provided through the first power channel according to the power;
wherein the controller reads a voltage value and a current value of the first power channel through the power array, and calculates the power of the power supply received by the component to be tested according to the voltage value and the current value.

2. The automatic power supply system of claim 1 , wherein the controller is further configured to control the power array to provide an initial voltage through the first power channel in an initial stage, calculate an effective resistance of the component to be tested, and determine an initial power specification of the power supply provided through the first power channel according to the effective resistance.

3. An automatic power supply system electrically coupled to a component to be tested, the automatic power supply system comprising:
a power array comprising a plurality of power channels, and configured to provide power supplies through the plurality of power channels, wherein the component to be tested is electrically coupled to a first power channel of the plurality of power channels and receives a power supply through the first power channel;
a controller electrically coupled to the power array, and configured to calculate a power of the power supply received by the component to be tested and adjust a power specification of the power supply provided through the first power channel according to the power; and
a measurement module electrically coupled to the controller and the component to be tested, and configured to measure a voltage and a current received by the component to be tested, wherein the controller calculates the power of the power supply received by the component to be tested according the voltage and the current measured by the measurement module.

4. The automatic power supply system of claim 3 , further comprising a temperature sensing module electrically coupled to the controller and the component to be tested, and configured to measure a temperature of the component to be tested, wherein the controller is further configured to stop providing the power supply through the first power channel when the temperature of the component to be tested is beyond a predetermined scope.

5. A method for operating an automatic power supply system, the automatic power supply system comprising a power array comprising a plurality of power channels, and a first power channel of the plurality of power channels is electrically coupled to a component to be tested, the method for operating the automatic power supply system comprising:
providing a power supply through the first power channel to the component to be tested;
reading a voltage value and a current value of the first power channel through the power array;
calculating a power of the power supply received by the component to be tested according to the voltage value and the current value; and
adjusting a power specification of the power supply provided through the first power channel according to the power.

6. The method for operating the automatic power supply system of claim 5 , further comprising:
controlling the power array to provide an initial voltage through the first power channel in an initial stage;
calculating an effective resistance of the component to be tested; and
determining an initial power specification of the power supply provided through the first power channel according to the effective resistance.

7. The method for operating the automatic power supply system of claim 5 , further comprising:
measuring a temperature of the component to be tested; and
stopping providing the power supply through the first power channel when the temperature of the component to be tested is beyond a predetermined scope.
