Abstract
A high voltage switch comprising: a high voltage power supply providing power greater than about 5 kV; a control voltage power source; a plurality of switch modules arranged in series with respect to each other each of the plurality of switch modules configured to switch power from the high voltage power supply, and an output configured to output a pulsed output signal having a voltage greater than the rating of any switch of the plurality of switch modules, a pulse width less than 2 μs, and at a pulse frequency greater than 10 kHz.
Claims19
A high voltage switch comprising:
- a high voltage power supply having a voltage greater than 5 kV;
- a first switch module comprising:
- a first switch having a first voltage rating;
- a first transformer electrically or inductively coupled with a control voltage power source and electrically or inductively coupled with the first switch, providing a voltage less than the first voltage rating;
- and
- a first switch trigger electrically or inductively coupled with the first switch;
- a second switch module arranged in series with the first switch module, the second switch module comprising:
- a second switch having a second voltage rating;
- a second transformer electrically or inductively coupled with the control voltage power electrically or inductively and electrically coupled with the second switch, providing a voltage less than the second voltage rating;
- and
- a second switch trigger electrically or inductively coupled with the second switch, and
- an output electrically or inductively coupled with the first switch module and the second switch module, and the output receiving pulses from the high voltage power supply greater than either the first switch voltage rating and/or the second switch voltage rating.
A high voltage switch comprising:
- a high voltage power supply providing power greater than about 5 kV;
- a control voltage power source;
- a plurality of switch modules arranged in series with respect to each other, each of the plurality of switch modules configured to switch power from the high voltage power supply, each of the plurality of switch modules comprising:
- a switch having a collector, an emitter, and a gate, and a voltage rating;
- a transformer electrically or inductively coupled with the control voltage power source and electrically or inductively coupled with the switch;
- and
- a gate trigger electrically or inductively coupled with the gate of the switch, wherein the switch is opened and closed based on a signal from the gate trigger;
- and
- an output configured to output a pulsed output signal having a voltage greater than the rating of any switch of the plurality of switch modules, a pulse width less than 2 μs, and at a pulse frequency greater than 10 kHz.
