Abstract

Inventia se refera la domeniul electronicii industriale si anume al redresoarelor comanda e cu tiristoare care lucreaza pe sarcina inductiva, mai ales când se utilizeaza transformatoare de impuls pentru comanda pe grila, constituind o perfectionare a inventiei principale, cu nr.97646. Ea rezolva generarea, cu un circuit mai simplu si cu mai multe facilitati, a unui tren de impulsuri cu durata atât a trenului, cât si a pauzei dintre impulsuri ajustabila prin tensiune. în aplicatia de la redresoarele comandate ce lucreaza pe sarcina inductiva, trenul de impulsuri poate înlocui un impuls lat de comanda pe grila, permitând reducerea puterii disipate pe jonctiunea grila-catod a tiristoarelor si reducerea substantiala a gabaritului si costului transformatoarelor de impulsuri.The invention relates to the field of industrial electronics, namely the thyristor controllers, which work on the inductive load, especially when using impulse transformers for command on the grid, constituting a refinement of the main invention, no. 977646. It solves the generation, with a simpler and more convenient circuit, of a pulse train with the duration of both the train and the tension-adjustable pulse pause. In the application of the rectifiers that work on the inductive load, the pulse train can replace a gentle command impulse on the grid, allowing for the reduction of the dissipated power on the grid-cathode junction of the thyristors and the substantial reduction of the gauge and cost of the pulse transformers.
