Abstract

A power supply test system includes a test chamber, a switch module, a temperature detecting unit, a control module, and a refrigerating and heating module. The test chamber accommodates a power supply. The switch module inputs a predetermined temperature value. The temperature detecting unit detects temperature signals in the test chamber. The control module receives the temperature signals. The refrigerating and heating module receives a first control signal from the control unit when a value of the temperature signal is less than the predetermined temperature value. The refrigerating and heating module heats the test chamber. The refrigerating and heating module receives a second control signal from the control unit when a value of the temperature signal is greater than the predetermined temperature value. The refrigerating and heating module refrigerates the test chamber until the value of the temperature signal is equal to the predetermined temperature value.

Description

BACKGROUND[0001]1. Technical Field[0002]The present disclosure relates to a power supply test system for testing reliability of a power supply.[0003]2. Description of Related Art[0004]Computer power supplies are capable of rectifying alternating current into direct current. The reliability of a power supply is measured by comparing the input and output voltages of the power supplies. Burn in testing is an important test in determining the reliability of the power supply. A typical burn in test uses a test chamber to test a power supply under different temperatures. However, the typical test chamber uses thermal resistors to heat the power supply. The temperature increases slowly and the temperature control may not be precise.[0005]Therefore there is a need for improvement in the art.BRIEF DESCRIPTION OF THE DRAWINGS[0006]Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale...
