摘　　要：提出一种基于DSP技术的控制方案,采用硬件防护与软件加固相结合的方式解决电磁干扰,研制了一套重频脉冲源系统。脉冲源可连续输出5个脉冲,脉冲幅值为50 kV,最小间隔100μs,并以10μs为步长可调。采用有界波模拟器试验系统验证该方案及软件加固技术的可行性。实验结果表明,采用软件加固技术的DSP系统在重频EMP模拟器的工作场区附近工作正常,具有较强的抗干扰能力。Against electromagnetic interference （EM1）, a method based on DSP control, combining hardware protection with software reinforcement, is proposed in this paper. A repetition rate pulse source system is developed. A pulse source provides 5-way repetition rate pulses of 50 kV, with a minimum gap of 100 μs between two neighboring ways, and the pulses can be regulated continuously in 10-μs steps. A bounded-wave simulator system is used to prove feasibility of the method and the software reinforcement technology. The experimental results show that the DSP system using software reinforcement technology is well capable of reducing EMI. The system works properly in a simulated environment of repetition rate electromagnetic pulses.
