In order to stimulate atmospheric pressure plasma (APP), it is usually demanded that the applied pulses is with kV amplitude, ns rising time and pulse width, and kHz repetitive frequency. Intensively, the pulse front edge and width are always required to be as short as possible. Fortunately, the pulse generating circuit based on avalanche transistor is much suitable for these parameter requirements. This paper summarized the pulse generating methods using avalanche transistors. Firstly, the basic principle and research status of the avalanche transistor were introduced. And then the research status and performance characteristics of the four typical avalanche transistor-based circuits were detailed, including the series-transistor circuit, Marx circuit, parallel-transistor circuit and pulse cut-off circuit. Thereafter, the key factors influencing output pulse parameters were theoretically analyzed, such as pulse amplitude, rising time, fall time, pulse width, repetitive frequency, efficiency and stability. At last, the research status and basic theory of three combined avalanche transistor-based circuits were presented, including the series-transistor Marx circuit, parallel-transistor Marx circuit and parallel Marx circuit.
