DISPOSITIVO DI DISINNESCO TOTALE PER LE VALVOLE DELL INVERTITORE DI UN CONVERTITORE A CIRCUITO INTERMEDIO CHE ALIMENTA UN MOTORE ELETTRICO

摘要

An improved auxiliary extinguishing arrangement for extinguishing the inverters in an intermediate link converter of the type having an impressed current and supplying an electric motor in which the output terminals of the intermediate link are bridged by a series circuit comprising a controlled and uncontrolled rectifier and a reversing choke with a commutation capacitor in parallel with the controlled rectifier and reversing choke thereby permitting effluence commutation at low speeds with a minimum number of components.
