Abstract

Improvements introduced in the object of the main patent number 371,993, granted on October 2, 1971, for: Improvements in separate extinguishing series inverters, consisting of two governed switches connected to a continuous power supply, to supply a load, and that each one comprises a governed rectifier, called the main rectifier, and a first extinguishing circuit of the main rectifier that has an auxiliary governed rectifier, called the extinction rectifier, whose first electrode is connected, with the electrode of equal polarity of the main rectifier, to said source, an oscillating, inductance and capacitor circuit charged by said source, mounted between the electrodes of said extinguishing rectifier, and a first diode that connects the second electrode of the extinguishing rectifier to the electrode of equal polarity of the main rectifier so to come to polarize in the opposite direction main rectifier when it is through, said main rectifier also being shunt by a second diode whose direction of conduction is opposite to that of said main rectifier, said electronic switches being mounted so that the two main rectifiers are in series, with the same direction of conduction, characterized in that in each governed switch, the components of said extinguishing circuit are dimensioned to cut a current that passes through said main rectifier whose value is less than a given first threshold value, which corresponds to the normal value of the current provided by said main rectifier, and because each governed switch also includes a second extinguishing circuit of said main rectifier, consisting of a second extinction governed rectifier, a second oscillating, inductance and capacitor circuit, and a third diode that connects said extinguishing rectifier ny to said main rectifier, mounted between the source and said main rectifier identically to the first extinguishing circuit but whose components are dimensioned to cut a current between said first threshold value and a second value corresponding to the maximum value of the current capable of passing through said main rectifier, said primary and second extinguishing circuits intervening simultaneously to cut a current, through the main rectifier, of a value greater than said first threshold value.
