Abstract
Abstract System for the electric supply of a variable capacitive load by means, for each of the phases of the load, of an independent inverter comprising controlled rectifiers such as thyristors, which is connected by its input terminals to a direct-current source, which may be a rectifier, and by its output terminals to the terminals of a matching network whose output terminals are connected to the load. The matching network is formed of a capacitor connected to the input terminals of the matching network, a transformer having a high magnetising current, a filtering circuit comprising two inductances of which one is connected in parallel with the same terminals as those of the capacitor and the other in series in the circuit connecting one terminal of the capacitor to the corresponding terminal of the primary winding of the transformer. The terminals of the secondary winding of the transformer are connected to the terminals of the load.
