Embodiment Construction

[0036] Please refer to figure 1 , is a schematic diagram of the structure of the power supply characteristic testing system of the present invention. The power characteristic testing system 1 is suitable for automatically measuring the power characteristic of a device under test 2, so as to assist the designer to design the required power specification correctly, save time and manpower. Wherein, the device under test 2 may be a DC / DC power converter (DC / DC Converter) or a low dropout linear regulator (LDO). Meanwhile, the device under test 2 has a power input terminal in and a power output terminal out. In the foregoing, the power supply characteristics include power supply characteristics such as voltage, current, and power.

[0037] refer again figure 1 The power characteristic testing system 1 includes a computer 10 , a communication interface 12 , a DC power supply 14 , an electronic load supplier 18 , an oscilloscope 16 and a heating device 19 . Wherein, the operator ...

Abstract

The invention relates to a system and a method for testing power supply properties. The system for testing the power supply properties comprises a computer, a DC power supply, an electronic load supply, an oscilloscope and a heater. An operator can operate the computer to control the DC power supply, the electronic load supply and the heater to respectively provide DC input voltage, virtual load and environmental temperature required by measurement for a device to be tested, and utilizes the oscilloscope to acquire the property value / wave of an input power supply and the property value / wave of an output power supply of the device to be tested; and the oscilloscope sends the property value / wave of the input power supply and the property value / wave of the output power supply back to the computer for the confirmation of the operator, and the aim of automatically testing the power supply properties of the device to be tested is achieved. The system and the method can automatically test the power supply properties of the device to be tested at a preset environmental temperature to achieve the aims of saving time and saving human resources, and simultaneously can ensure that the device to be tested is in accordance with the requirement of each power supply property at the design stage.

Description

technical field [0001] The invention relates to a power supply characteristic test system, in particular to a test system capable of automatic testing-the power supply characteristic of a device to be tested. Background technique [0002] The so-called DC / DC converter (DC / DC Converter) is a switching power converter that converts a DC voltage into a DC voltage of a different voltage. With the advancement of the electronics industry, various electronic products have come out one after another, but the supply voltages required by different electronic products are often different. Therefore, it is necessary to use DC / DC converters to provide DC voltage conversion to meet the needs of electronic products. electricity demand. [0003] After the design of the DC / DC converter is completed, it is necessary to perform tests on various power supply characteristics before entering the mass production stage. In the test stage, it is usually necessary to test the DC / DC converter under n...
