  • Patent number: 9088207
    Abstract: One example embodiment may include a power supply system. The power supply system may include a main capacitor and a boost converter. The main capacitor is used to generate an electrical pulse. The boost converter is configured to be coupled to the main capacitor. Additionally, the boost converter includes a compensator supply including an energy storage capacitor that can store electrical energy. The boost converter also includes and a compensator inductor that receives the electrical energy from the compensator supply and is configured to supply electrical energy to the main capacitor when the main capacitor is generating the electrical pulse.
    Type: Grant

  • Patent number: 7554221
    Abstract: Systems and methods for generating a high voltage pulse. A series of voltage cells are connected such that charging capacitors can be charged in parallel and discharged in series. Each cell includes a main switch and a return switch. When the main switches are turned on, the capacitors in the cells are in series and discharge. When the main switches are turned off and the return switches are turned on, the capacitors charge in parallel. One or more of the cells can be inactive without preventing a pulse from being generated. The amplitude, duration, rise time, and fall time can be controlled with the voltage cells. Each voltage cell may also includes a balance network to match the stray capacitance seen by each voltage cell. Droop compensation is also enabled.
