Abstract

The static converter of the invention comprises a central processor (15) measuring the output voltage (TM3), the output current (TM4), the rectifier current (S) and the reverse bias time (8) of the thyristors of the switch (5). From this information it drives, through interfaces (17, 18, 20) the starting thyristors (6) comprising a series resonating circuit intitiating the oscillations of the parallel resonant load circuit (2,3).
