Abstract
A Marx high voltage generator with a fast rise time. Photoconductive semiconductor switches are sequentially triggered by a single laser via fiber optic bundles of different lengths. The switches serve to series connect a group of charged capacitors. Output is taken from the last capacitor which receives the voltage accumulated on all of the previous capacitors. Proper timing of the activation of each switch produces a fast rise time.
Claims6
A device comprising:
- a plurality of means for electrostatic storage connected in parallel;
- a plurality of optically controlled switches having a first optically controlled switch, said switches being connected in series between pairs of said means for electrostatic storage;
- means for independently activating the plurality of serially connected, optically controlled switches in a controlled sequential manner beginning with the first switch so that each successive switch is activated upon the arrival of the voltage wavefront which is generated by the activation of the first switch and which propagates in the direction of the remaining switches.
