Description

technical field

[0001] The present invention relates to the field of power supply health assessment, in particular to a power supply health assessment method and device. Background technique

[0002] The normal operation of all kinds of electronic and electrical equipment in modern society is inseparable from reliable power supply. With the development of power electronics technology, switching power supply has been widely used due to its advantages of high conversion rate, high power density, good stability and small volume and weight. application. Switching power supply uses modern power electronics technology to maintain the output voltage stability by controlling the duty cycle of the power switch tube. Compared with the traditional linear power supply, it has obvious advantages in conversion rate.

[0003] As the power supply unit of many electronic and electrical equipment, DC / DC (direct current to direct current) switching power supply is often one of the components ...
