Abstract

The invention provides a power supply health assessment method and device, and the method comprises the steps: collecting the input data and output data of a power supply, carrying out the calculationaccording to the input data and the output data, obtaining the conversion rate of the power supply, and obtaining the preset health degree-according to the preset health degree-. And calculating thehealth degree of the power supply according to the conversion rate function and the conversion rate. The method has low requirements on parameter detection, can be used for various power supplies, andfurther can detect and evaluate the health state of the power supplies in real time when the power supplies work.

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 ...
