Embodiment Construction

[0013] see figure 1 , is a system architecture diagram of the power supply circuit tolerance design optimization system of the present invention. The power circuit tolerance design optimization system 10 is a programmable system running on a processor. The processor is connected with an input unit 20 , an output unit 30 and a storage unit 40 .

[0014] The input unit 20 can be a button, a touch screen, etc., and is used to receive user input. The output unit 30 can be a display for outputting the results generated by the system 10 for optimizing the tolerance design of the power supply circuit. A database is stored in the storage unit 40, including a BOM table, which contains several types of components corresponding to different circuits, and all types and corresponding parameters of each type of components. Specifically, the component refers to electronic devices such as resistors, capacitors, or inductors. It should be noted that two resistors with different resistance ...

Abstract

The invention provides a system and a method for optimizing the tolerance design of a power circuit. The method comprises the following steps: setting corresponding transmission functions and parameters needing to be calculated according to different circuits; obtaining a plurality of types of elements corresponding to a circuit, all models of each type of elements and corresponding parameters; calculating standard error values corresponding to all models of elements in each type of elements according to a standard error value calculation formula; comparing the standard error values corresponding to all models of elements in each type of elements, and determining the model with a maximum error value; substituting the parameters corresponding to all types of elements of the model with the maximum error value into the transmission function for calculation, and judging whether the elements accord with the standard; outputting a judging result. According to the system and the method for optimizing the tolerance design of the power circuit disclosed by the invention, data search, input and calculation are completed by utilizing programmable software, so that the manpower and time are effectively saved, and the degree of accuracy is improved.

Description

technical field [0001] The invention relates to a power circuit tolerance design optimization system and method, in particular to a power supply circuit tolerance design optimization system and method which can save manpower and time. Background technique [0002] Power supply circuit tolerance design optimization is to collect the impact of environmental stress on individual electronic components, through circuit analysis and the use of statistical methods, directly predict the impact of environmental stress on the circuit, and then determine whether various environmental stresses are possible cause this circuit to fail. There are many types of electronic components used in a project performing power circuit tolerance design optimization. Components of the same type also have different parameters and degrees of sophistication due to different suppliers. Therefore, when conducting the optimization analysis of the tolerance design of the power circuit, the number of electro...
