Abstract: A high power (HP) generator includes a plurality of low power (LP) generators, a coupling in which the plurality of LP generators is electrically connected, and a control unit. During operation, at least in some states of the HP generator, a coupling-value at an output of the coupling is higher than an LP-generator-value at an output of one of the plurality of LP generators. The control unit is configured to select a respective contribution of each of the plurality of LP generators in order to generate a rise and/or a decay of a pulse at the output of the coupling. The HP generator further includes a respective damping circuit positioned between each pair of adjacent LP generators of the plurality of LP generators in an open chain configuration. The damping circuit includes a resistor and/or an inductor.

Abstract: A high power (HP) generator includes a plurality of low power (LP) generators, a coupling in which the plurality of LP generators is electrically connected, and a control unit. During operation, a coupling-value at an output of the coupling is higher than an LP-generator-value at an output of one of the plurality of LP generators. The control unit is configured to select a contribution of each LP generator to an output value of the HP generator, in a way that one or a combination of following is accomplished: (i) the output of the coupling and/or the output of the HP generator is a step function, (ii) the plurality of LP generators is activated sequentially during a pulse, (iii) at least one amplitude step is lower than 1 kV, and (iv) the plurality of LP generators is connected by switching only.

The control unit is configured to select a respective contribution of each LP generator in order to generate a rise and/or a decay of a pulse at the output of the coupling. A charging energy of the LP generators is supplied over a transformer with a primary winding and a secondary winding for each LP generator. The secondary winding is connected to a rectifier, which is connected to the energy storage component of the corresponding LP generator, and/or a plurality of the primary windings is connected in series.
