摘　　要：为更加快速稳定有效地控制高压脉冲电场设备,提高设备的稳定性、可调性和易用性,研制了1套基于现场可编程门阵列（FPGA）的高压脉冲电场（PEF）设备控制器.控制器包括用于人机交互操作的工控计算机触摸屏终端、执行控制任务的FPGA控制器及其附属外围电路3部分.FPGA控制器采用Cyclone系列的高速处理芯片,附属电路包括触发信号电平转换、光电隔离部分以及电压电流反馈部分.控制器能够连续调节脉冲波形的频率、占空比,以及实现对于高压IGBT的触发和过流监控,控制脉冲电场的电压电流等功能.通过实验室测试证实,系统较好地实现了设计目标,研制出频率（10～104 Hz）、占空比（2～10μs）、电压（0～35kV）均可连续实时调节的高压脉冲电场发生器,同时其具有很强的扩展能力,能够配合新型脉冲发生器使用.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.
