Claim 0:
1. A nanosecond pulser circuit comprising:
a high voltage power supply, wherein the high voltage power supply provides DC power with a voltage greater than 1 kV;
a plurality of switches electrically coupled with the high voltage power supply, the plurality of switches switch voltage from the high voltage power supply at high frequencies;
a transformer having a primary side and a secondary side, the plurality of switches electrically coupled with the primary side of the transformer; and
an energy recovery circuit electrically coupled with the secondary side of the transformer, the energy recovery circuit comprising:
an energy recovery inductor electrically coupled with the high voltage power supply; and
a diode disposed in series with the energy recovery inductor and arranged to restrict current flowing from the high voltage power supply through the energy recovery inductor to a load located on the secondary side of the transformer.
