Abstract
(EN)
Provided are a multifunctional machine reactor and a multifunctional machine output circuit. The reactor comprises a magnetic core, a winding, and a base. The left and right sides of the magnetic core are provided with a winding L1 and a winding L2, respectively; and the base is provided at the bottom of the magnetic core. Both the winding L1 and the winding L2 are composed of 11 turns of bare copper windings to form a mutual-inductance type reactor, and separation plates are used to separate the turns with gaps reserved therebetween. The magnetic core is a CD-type silicon steel sheet iron core, and the base has a horizontal base structure. The reactor is separately connected to the "+" and "-" ends of a multifunctional-machine secondary inverter circuit. Current flow directions of the two windings are opposite, and the two windings operate in an alternating manner. When a current flows through one winding, the other winding is disconnected and releases energy to the winding through which a current flows, so as to ensure that output circuit inductance values of the positive and negative polarities are balanced during AC output, and ensure rapid circuit release of reverse electromotive force during disconnection, thereby greatly improving a zero-crossing speed of an AC output waveform conversion and ensuring the stability of an AC arc.

L'invention concerne un réacteur de machine multifonction et un circuit de sortie de machine multifonction. Le réacteur comprend un noyau magnétique, un enroulement et une base. Les côtés gauche et droit du noyau magnétique sont respectivement pourvus d'un enroulement L1 et d'un enroulement L2 ; et la base est disposée au fond du noyau magnétique. L'enroulement L1 et l'enroulement L2 sont composés de 11 tours d'enroulements de cuivre nu pour former un réacteur de type à inductance mutuelle, et des plaques de séparation sont utilisées pour séparer les spires par des espaces réservés entre eux. Le noyau magnétique est un noyau de fer en tôle d'acier au silicium de type CD, et la base a une structure de base horizontale. Le réacteur est connecté séparément aux extrémités "+" et "-" d'un circuit onduleur secondaire de machine multifonctionnelle. Les sens de circulation de courant des deux enroulements sont contraires, et les deux enroulements fonctionnent en alternance. Lorsqu'un courant circule à travers un enroulement, l'autre enroulement est déconnecté et libère de l'énergie vers l'enroulement à travers lequel circule un courant, de façon à garantir un équilibre de valeurs d'inductance de circuit de sortie des polarités positive et négative pendant une sortie de courant alternatif, et à garantir un relâchement rapide de force électromotrice inverse de circuit pendant la déconnexion, ce qui permet d'améliorer considérablement la vitesse de passage au zéro d'une conversion de forme d'onde de sortie de courant alternatif ainsi que de garantir la stabilité d'un arc de courant alternatif.
