Abstract

Inventia se refera la un dispozitiv de formare a impulsurilor pentru comanda tiristoarelor pentru un invertor trifazat cu circuit de stingere divizat si constituie o perfectionare a inventiei principale cu descrierea nr. 95119. Dispozitivul, conforminventiei, este caracterizat prin aceea ca informatiile din circuitul de forta; tensiunea pe condensatoarele de stingere, starea de conductie a tiristoarelor sunt culese cu ajutorul unor optocuploare si a unor traductoare de curent; sunt formate cuaj utorul unor redresoare ideale si a unor comparatoare si sunt prelucrate apoi cu o schema logica obtinându-se semnalele de validare a impulsurilor de comanda a tiristoarelor principale.The invention relates to a pulse generating device for commanding thyristors for a three-phase inverter with a split extinguishing circuit and constitutes a refinement of the main invention with the description no. 95119. The device according to the invention is characterized in that the information in the force circuit; the voltage on the extinguishing capacitors, the conduction state of the thyristors are collected by means of some optocouplers and some current transducers; are formed with the quadrant of some ideal rectifiers and comparators and are then processed with a logic scheme obtaining the signals for command control pulses of the main thyristors.
