[0020] Combine below figure 1 The first embodiment of the present invention is described. The robust parameter design method comprehensively considering manufacturing and temperature noise described in this embodiment specifically includes the following steps:

[0021] S1: Based on the basic data of controllable factors and noise factors (manufacturing and temperature), establish a robust parameter design analysis table considering comprehensive noise; a typical robust design includes inner and outer tables. The controllable factors are arranged in the inner surface to investigate the change of the average performance; the error factors are arranged in the outer surface to simulate various disturbances and are used to inspect the robustness of the product quality.

[0022] S2: Obtain the target simulation results of the robust parameter design analysis table from the calculation of the simulation model;

[0023] S3: Obtain the central value and variance from the statistics of...

Abstract

The invention discloses a parameter design method of an electronic system comprehensively considering manufacturing and temperature noise. The method comprises following steps: establishing a robustness parameter design analysis table from controllable factors and basic data of first parameter noise factors and second parameter noise factors; calculating a target simulation result of the analysis table; performing second parameter statistics of inner and external table to obtain center value and variance; performing normalization; determining first parameter noise weight and second parameter noise weight to obtain second parameter noise assessment value; filling the second parameter noise assessment value in the inner and external table and performing statistics on the signal to noise ratio and sensitivity characteristic value corresponding to the inner table; performing variance analysis on the signal to noise ratio and sensitivity characteristic value to determine optimized parameter level combination; obtaining output distribution under second parameter of different designs before and after optimization through simulation; if the optimization scheme satisfies requirements, then optimization is stopped; otherwise, adjusting the first parameter noise weight and the second parameter noise weight and optimizing the parameter level combination again.

Description

technical field [0001] The invention relates to the technical field of electronic system performance optimization, in particular to an electronic system parameter design method that comprehensively considers manufacturing and temperature noise. Background technique [0002] Power electronic equipment is closely related to people's work and life, and the development of power electronic equipment cannot be separated from the improvement of power supply. Compared with traditional linear power supplies, switching power supplies, as a green power supply, are widely used in power electronic equipment in various industries such as electric power, aerospace, and information. In the circuit, the switching power supply is mainly responsible for functions such as isolation transformation and power transmission, and supplies power to the electronic system. Because it is directly connected with electrical equipment, its stability and reliability are prerequisites for the normal operatio...
