Patent ID: 7755217

Claim:
A method for controlling a pulse generator comprising a plurality of cells, each cell including a controllable semiconductor switch and a capacitor for generating a voltage pulse through series connection and/or parallel connection of the capacitors by the semiconductor switches, the method comprising: performing in a control circuit: generating a first switch-on signal for switching the respective semiconductor switch of a cell to a conducting state, measuring a system response for each cell of the plurality of cells, wherein the system response is dependent on a switching of a respective semiconductor switch of the cell to the conducting state, measuring a switch-on time difference for each cell of the plurality of cells, wherein for each cell the switch-on time difference being measured between a first switch-on signal for switching the respective semiconductor switch of the cell to the conducting state and the measured system response dependent on the switching of the respective semiconductor switch to the conducting state, controlling the semiconductor switches of each cell for the voltage pulse as a function of the switch-on time difference, and generating a second switch-on signal for each cell as a function of the measured switch-on time, wherein the second switch-on signal is generated in such a time-shifted manner that the system response of all cells of the plurality occurs simultaneously, the system response being dependent on the switching to the conducting state.
