Nanosecond pulser bias compensation

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 an amplitude greater than 1 kV, a pulse width less than 500 ns, and a pulse repetition frequency greater than 1 kHz;
• wherein the transformer provides galvanic isolation between the output and the plurality of switches;
• wherein the plurality of switches are disposed between the power supply and the transformer.
