Abstract
An assembly is made enabling an inverter of a high-voltage generator to pass from a full-bridge use to a half-bridge use, in replacing a connection circuit of a mid-point of a first rectifier of this generator at a mid-point of the inverter by a circuit that is frequency controlled at the rate at which the inverter itself is controlled. By this approach, the two assemblies are made compatible and it becomes possible to pass from one assembly to the other as a function either of a high power to be supplied or of a ripple, which cannot be tolerated, of a residual voltage rectified by a second rectifier.
