Abstract

The embodiment of the invention provides a DC / DC switching power supply function test system comprising a test case, wherein a support frame is installed on the test case, and a DC / DC switching powersupply to be tested is fixed on the test case; a driving assembly mounted on the support frame; and a connection test assembly comprising a probe, wherein the probe is installed at the lower part of the driving assembly, and the probe is in press fit with the DC / DC switching power supply to be tested under the driving of the driving assembly so as to acquire the performance parameters of the DC / DCswitching power supply to be tested. According to the DC / DC switching power supply function test system provided by the embodiment of the invention, power is supplied through probe pressing, and operation information of different circuits on the DC / DC switching power supply is acquired, so that automatic test of the DC / DC switching power supply is realized, the test efficiency is high, and the operation is simple and convenient. And the DC / DC switching power supply only needs to be placed on the test case, and the switch is started, so that the workload of operators is reduced, and the laborcost is reduced.

Description

technical field [0001] The invention relates to the technical field of DC / DC switching power supply testing equipment, in particular to an automatic testing system for a DC / DC switching power supply. Background technique [0002] DC conversion is to control the ratio of the output voltage to the input voltage by controlling the opening and closing of the switching tube. Adjust the duty cycle to regulate the output voltage. [0003] DC / DC switching power supply is a power supply that uses modern power electronics technology to control the time ratio of the switching tube on and off to maintain a stable output voltage. A switching power supply is generally composed of a pulse width modulation (PWM) control IC and a MOSFET. With the development and innovation of power electronics technology, switching power supply technology is constantly innovating. At present, switching power supply is widely used in almost all electronic equipment due to its small size, light weight and h...
