A single driving voltage sharing and driving coupled series IGBT is designed in order to provide pulse power with adjustable voltage

frequency and pulse width for dielectric barrier discharge. In this series circuit

a coupling circuit of a dynamic averaging voltage and a driving signal output is connected in parallel with each IGBT.When the circuit turns on or off

the voltage between each IGBT will be restricted under rated value

and supply a driving or cut-off signal for the next IGBT. The feasibility of the circuit principle is verified

and the criteria of the circuit components are explored by simulated. In experiment

the voltage can be adjusted between 0 and 15 kV

the frequency can vary from 0 to 1 kHz

the pulse width can be regulated within certain range with 8 series IGBT circuits.Dielectric barrier discharge is achieved by this series circuit. The traditional multi driving series IGBT must be isolated from high voltage power supply

and single driving series IGBT works with a fixed voltage and pulse width. The series circuit in this paper solves both problems and is also applicable for MOSFET

which owns great potential and worthwhile further study.
