Atmospheric-pressure non-equilibrium plasma jets（APNP-Js） are generated in the open space

rather than inside a narrow discharge gap. This unique property advances the wide applications of APNP-Js

such as material surface treatment

nanotechnology and plasma medicine. In the past decade

the development of APNP-Js is blooming. APNP-Js has been considered as one of new key technologies for low-temperature plasma applications. In this paper

from the perspective of power supply

several typical APNP-Js driven by direct current（DC） power supply

alternative current（AC） power supply

radio frequency（RF） power supply

pulsed power supply

and double power supplies are introduced first. Then

a comparison among the characteristics of APNP-Js driven by different power supplies is presented. It is found that

with the same consumed power

APNP-Js driven by pulsed power are longer and more reactive

but remain at room temperature. The effects of parameters of the power supplies on APNP-Js are analyzed further. It is revealed that

1 As the driven frequency increases from 1 Hz into RF range

the length of APNP-Js decreases

plasma bullets turns into continuous columns in the dynamics of APNP-Js. 2 As the pulse rising time decreases from several μs to 50 ns

the length of APNP-Js increases and the electron temperature becomes higher. 3 By comparing the characteristics of APNP-Js driven by positive and negative applied voltage

it is found that APNP-Js with negative polarity are shorter

propagating slower

but are of higher electric field strength in the plasma column behind the streamer head. In the last

the relationship between APNP-Js and the driven power supply is discussed

and several important open issues are proposed

such as how to generate more reactive APNP-Js with less input power

how to allocate and optimize the energies coupling into plasmas.
