介绍了一种可以完成脉宽、幅值、频率可调、十路脉冲输出且延时可调功能的程控脉冲发生器。硬件主要包括主电源和辅助电源、功率放大电路、控制系统处理器、数字键盘和液晶显示屏。该脉冲发生器输出脉冲宽度可在1~30 μs间调节，脉冲幅值在1~15 V间调节，输出脉冲频率范围为1 Hz~30 kHz，十路脉冲输出中每路脉冲之间可以在0~1 ms范围内精确调节。该脉冲发生器可为多个脉冲源的并联运行提供延时触发，为多个绝缘栅双极型晶体管(IGBT)开关串联提供同步触发。

This paper introduces a type of program-controlled pulse generator, which can adjust the amplitude, width and frequency of the output pulses, and precisely control the delay time of the ten-channel output pulse sequences. The pulse generator includes the main and auxiliary power supplies, power amplifier circuit, controlling system, digital keyboard and liquid crystal display. The output pulses have parameters adjustable within following ranges: frequency range 1 Hz-30 kHz, pulse width range 1-30 μs, and pulse amplitude range 1-15 V; the delay of ten branches can be precisely adjusted within 0-1 ms. The pulse generator can provide delay triggers for pulse sources in parallel, and synchronized triggers for IGBT switches in series.
