High-power switching module for the direct pulse energy feeding of a consumer

A high-power switching module for the direct pulse energy feeding of a consumer with a plurality of switching stages connected in series, each switching stage comprising:

• a semiconductor switch with collector terminal, emitter terminal and control terminal, which depending on the voltage present at the control terminal comprises a switched-on state, in which a current flows between the collector terminal and the emitter terminal, and a switched-off state, in which no current flows between the collector terminal and the emitter terminal,
• a driver assembly acting on the semiconductor switch, the driver assembly comprising two switches for controlling the control terminal of the semiconductor switch and also an energy store, which provides energy for switching on the semiconductor switch,
• a balancing capacitance connected in parallel with the semiconductor switch between collector terminal and emitter terminal,
• a coupling element and an energy buffer store,
• the coupling element coupling a primary circuit comprising the balancing capacitance and the semiconductor switch to a secondary circuit comprising the energy buffer store,
• the coupling element being provided and embodied for obtaining energy of the balancing capacitance and delivering this energy to the energy buffer store during the on phase of the semiconductor switch, and
• the energy buffer store being provided and embodied for delivering the obtained energy to the energy store of the driver assembly when the semiconductor switch is in the switched-off state.
