为有效控制固态功率调制设备,提高系统的可调性和稳定性,介绍了一种基于现场可编程门阵列(FPGA)和微控制器(MCU)的多路高压IGBT驱动触发器的设计方法和实现电路。该触发器可选择内或外触发信号,可遥控或本控,能产生多路频率、宽度和延时独立可调的脉冲信号,信号的输入输出和传输都使用光纤。将该触发器用于高压IGBT(3300V/800A)感应叠加脉冲发生器中进行实验测试,给出了实验波形。结果表明,该多路高压IGBT驱动触发器输出脉冲信号达到了较高的调整精度,频宽’脉宽及延时可分别以步进1Hz、0.1μs、0.1μs进行调整,满足了脉冲发生器的要求,提高了脉冲功率调制系统的性能。
In order to effectively control the solid state power modulation device and improve the adjustability and stability of the system, a design method of a multi-channel high-voltage IGBT driving trigger based on a field programmable gate array (FPGA) and a micro-controller Realize the circuit. The trigger can be selected within or outside the trigger signal, remote control or the control, can produce multiple channels of frequency, width and delay adjustable pulse signal, the signal input and output and the use of optical fiber transmission. The trigger was used in high voltage IGBT (3300V / 800A) induction stack pulse generator experimental test, given the experimental waveform. The results show that the multi-channel high-voltage IGBT drive flip-flop output pulse signal to achieve a higher adjustment accuracy, bandwidth ’pulse width and delay can step 1Hz, 0.1μs, 0.1μs to adjust to meet the pulse generator Requirements, improve the performance of the pulse power modulation system.
