Description

technical field [0001] The invention relates to an automatic test system for a DC / DC converter, which belongs to the field of electric signal test. Background technique [0002] As a device that converts one DC voltage to another DC voltage and provides a continuous and stable DC voltage at the output of the device, DC / DC converters are widely used in the fields of aerospace, communication equipment, and household appliances. [0003] With the rapid development of electronic technology, the extensive use of semiconductor technology, sealed-turn technology and high-frequency soft switches has made DC / DC converters develop in the direction of higher power density and higher conversion efficiency. The DC / DC converter itself Although the function is simple, its interior is composed of passive components, active components, power devices, etc., forming a small electronic system. For key power devices, the reliability of the device is particularly critical. Therefore, before the d...
