Claim 10:
11. A bipolar pulsing power supply comprising:
a power source that provides a voltage greater than 100 V;
a first switch circuit electrically coupled with the power source, the first switch circuit comprises one or more switches selected from the group consisting of an IGBT switch, MOSFET, FETs, SiC switch, and GAN switch;
a second switch circuit electrically coupled with the power source, the second switch circuit comprises one or more switches selected from the group consisting of an IGBT switch, MOSFET, FETs, SiC switch, and GAN switch;
a third switch circuit electrically coupled with the first switch and ground, the third switch circuit comprises one or more switches selected from the group consisting of an IGBT switch, MOSFET, FETs, SiC switch, and GAN switch;
a fourth switch circuit electrically coupled with the second switch and ground, the fourth switch circuit comprises one or more switches selected from the group consisting of an IGBT switch, MOSFET, FETs, SiC switch, and GAN switch, wherein the first switch circuit, the second switch circuit, the third switch circuit, and the fourth switch circuit are arranged in an H-bridge configuration;
an output electrically coupled at a point between the first switch circuit and the third switch circuit and electrically coupled at a point between the second switch circuit and the fourth switch circuit, the output producing a negative pulse with a voltage less than −1 kV when the second switch circuit and the third switch circuit are closed and the first switch circuit and the fourth switch circuit are open, the output producing a positive pulse with a voltage greater than 1 kV when the first switch circuit and the fourth switch circuit are closed and the second switch circuit and the third switch circuit are open, wherein the positive pulse has a rise time less than about 50 ns; and wherein the negative pulse has a rise time less than about 50 ns.
