A high precise and high voltage pulse generator made up of high-power IGBT and pulse transformer is proposed. It utilizes PC, MCU and Complex Programmable Logic Device (CPLD) to generate trigger signals. Pulse frequency, width and numbers of the high voltage pulse generator can be controlled by PC in some ranges. The power is very suitable for the research of non-thermal effect on pulsed electric fields,and can provide the increase and decrease of the pulse width by 1 μs.
