A plasma jet excited by pulsed power is a promising approach for producing non-thermal plasmas
at atmospheric pressure. Pulsed power generators vary widely in performance and should be
selected according to the requirements of each application. In this paper, a repetitive
microsecond-pulse generator is constructed using cascading power modules where solid-state
switches are the key units. The generator is capable of providing repetitive pulses with a voltage
up to 10 kV, pulse duration of a few microseconds, and repetition frequency of up to 5 kHz. The
output pulse voltage can be adjusted by varying the ac input voltage, and the pulse width and
frequency can be changed by the driving signal of the IGBTs. This generator has been
successfully used for plasma jet applications.
