Abstract

The invention provides a testing device and method for a DC / DC converter. The device comprises a test board, a programmable control power supply, a programmable control electronic load, a testing device body and a control device. The test board is connected with the programmable control electronic load and the testing device body. The control device is connected with the programmable control power supply, the programmable control electronic load and the testing device body. The control device is used for providing voltage for the DC / DC converter to be tested through control over the programmable control power supply, and controlling the programmable control electronic load to provide a load for the DC / DC converter. According to a set period, the testing device body is controlled to detect the testing parameters, in the testing environment, of the DC / DC converter to be tested, and the testing parameters detected by the testing device body are read. The testing parameters are tested through the testing device body and transmitted to the control device to be recorded and processed, and therefore while consumed labor is reduced, testing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of voltage conversion equipment testing, in particular to a DC / DC converter testing device and a DC / DC converter testing method. Background technique [0002] The DC / DC converter is a voltage converter that effectively outputs a fixed voltage after changing the input voltage. It is widely used in remote and data communications, computers, office automation equipment, industrial instrumentation and other fields. With the development of the electronic industry, higher requirements are put forward for the reliability of DC / DC converters. Factors that determine the reliability of DC / DC converters include system design (including technical solutions and circuit topology design, interface design, environmental test condition adaptability design, etc.), inherent quality of components and product assembly process defects, and voltage, current and The influence of temperature and other stresses on its reliability. ...
