Abstract

Inventia se încadreaza în solutiile pentru îmbunatatirea randamentului si micsorarea solicitarilor în tensiune a invertoarelor cu tiristoare. în acest scop încarcarea condensatoarelor de comutatie se face printr-un circuit inductiv iar energia înmagazinata în inductanta este recuperata cu ajutorul unui transformator de curent în circuitul surselor de alimentare. Folosirea unui transformator de curent prezinta avantajul ca tensiunile induse se mentin în limite nepericuloase pentru dispozitivele semiconductoare, iar tensiunea cu care se încarca suplimentar condensatorul este mica.The invention encompasses solutions for improving efficiency and reducing voltage stresses of thyristor inverters. For this purpose the charging of the switching capacitors is made by an inductive circuit and the energy stored in the inductor is recovered by means of a current transformer in the supply source circuit. The use of a current transformer has the advantage that induced voltages remain within non-hazardous limits for semiconductor devices, and the voltage with which the capacitor is additionally charged is low.
