1. A high voltage power system comprising:
a power supply;
a plurality of switches electrically coupled with the power supply;
a transformer comprising:
a transformer core;
a primary winding wound around the transformer core, the primary winding electrically coupled with the plurality of switches; and
a secondary winding wound around the transformer core; and
an output electrically coupled with the secondary winding of the transformer, wherein opening and closing the plurality of switches produces an output of a plurality of high voltage pulses with a pulse width less than 500 ns, an amplitude greater than 1 kV, and a pulse repetition frequency greater than 1 kHz;
wherein the transformer provides galvanic isolation between the output and ground;
wherein the plurality of switches are disposed between the power supply and the transformer.
