Abstract
A nanosecond pulser is disclosed. In some embodiments, the nanosecond pulser may include one or more switch circuits including one or more solid state switches, a transformer, and an output. In some embodiments, the transformer may include a first transformer core, a first primary winding wound at least partially around a portion of the first transformer core, and a secondary winding wound at least partially around a portion of the first transformer core. In some embodiments, each of the one or more switch circuits are coupled with at least a portion of the first primary winding. In some embodiments, the output may be electrically coupled with the secondary winding and outputs electrical pulses having a peak voltage greater than about 1 kilovolt and a rise time of less than 150 nanoseconds or less than 50 nanoseconds.
