摘　　要：介绍了基于分数比可饱和脉冲变压器的一体化磁开关组成及其工作原理,可实现固态磁开关、脉冲调制以及电压升压等功能,并给出了该一体化磁开关的三种典型应用,一是应用在高压脉冲触发器中,可实现触发器电压大于100 kV,30 Hz重复频率下抖动小于5 ns;二是用于微秒准方波产生,实现了电压幅值大于50 kV,100 Hz长时间运行;三是作为低阻脉冲形成线的主开关,利用双开关调制产生百纳秒方波脉冲,以实现脉冲功率装置的轻量化。基于分数比可饱和脉冲变压器的一体化磁开关是一种将磁开关和脉冲变压器集成紧凑的脉冲功率器件,能够兼顾变压器高升压比和磁开关低次级饱和电感,对实现脉冲功率器件的固态化、集成紧凑化具有重要的意义。This paper introducesd the composition and working principle of the integrated magnetic switch based on fractional-turn ratio saturable pulse transformer.The integrated magnetic switch can realize the functions of solid-state magnetic switch,pulse modulation and voltage boost.Three typical applications of the integrated magnetic switch are also provided.First,it can be applied in high-voltage pulse trigger,which can realize the voltage greater than 100 kV,and jitter less than 5 ns at 30 Hz;Second,it is used for microsecond quasi-square pulse generation,producing larger than 50 kV and microsecond-range pulses continuously at 100 Hz;Third,as the main switch of the low-resistance pulse forming line,to output square pulses of 100 ns with dual-switch modulation technique to realize the lightweight of the pulse power device.The integrated magnetic switch based on fractional-turn ratio saturable pulse transformer is a compact pulse power device,which can take into account the high boost ratio of transformer and the low secondary saturation inductance of magnetic switch.It is of great significance for the realization of solid state and compactness of pulse power device.
