英文摘要：

To control the high-voltage pulsed electric field（PEF） generator faster, more stable, and more effective, a new controller for high-voltage pulsed electrical field device based on field-programmable gate array（FPGA） was developed. The controller consists of an industrial control computer with a touch screen used for man-machine operation, a field-programmable gate array （FPGA） controller, and other external circuits. FPGA uses high speed chipsets from Cyc- lone. External circuits consists of the trigger-signal voltage convertor, photoelectric isolation, and voltage-current feedback, The controller can adjust the output wave＇s frequency and duty cycle continuously, and can realize the drive of high-voltage IGBTs, the surveillance of IGBT＇s overcurrent as well as the control of the voltage and current of PEF output. The tests i：a laboratory confirm that the system has achieved the design goat, can produce high voltage pulsed-electrical-field output wave frequency from 10 to 10 kHz, duty cycle from 2 to 10 μs and voltage high to 35 kV, and has the extended capability. The new controller enlarges the equipment flexibility and portability and meets the re- quirements of the new high-voltage pulse electric field equipment control system.
