Abstract

The invention discloses a reactor design method based on a visualization algorithm. According to the method, the reactor iron core magnetic path length l, the reactor iron core cross section S and the reactor coil turn number N are used as three variables, the value of the minimum volume V of a reactor is obtained under the limitation conditions that the inductance value L of the reactor and the volume V of the reactor meet the value of the inductance value L and simultaneously meet the coil turn number N and the iron core cross section S, and then, the reactor iron core magnetic path length l, the reactor iron core cross section S and the reactor coil turn number are obtained through combining an inductance value change trend figure and a volume change trend figure. The reactor design method has the advantages that the simplification problem is solved through the visualization algorithm, the design process is relatively visual, simple and convenient, and in addition, the function change condition can be conveniently observed.

Description

technical field [0001] The invention relates to a reactor design method, in particular to a reactor design method based on a visualization algorithm. Background technique [0002] With the rapid development of power electronic technology, various power electronic devices are widely used in many fields such as power system, industry, transportation, family and so on. The resulting harmonic problem is becoming more and more serious. most important question. Unlike other electrical components, it is difficult for users to purchase inductors that meet their own requirements. To design a magnetic component that meets the electrical performance conditions, it is necessary to comprehensively consider its cost, volume, weight and other difficulties. [0003] The commonly used rectifier circuit adopts a three-phase bridge structure. Although the capacitor filter circuit is required by many designers, its output voltage distortion rate is relatively large, which will affect the elect...
