Embodiment 1

[0028] Such as figure 1 with figure 2 As shown, a pulse modulator includes a power supply, a control unit, an energy storage unit, a TESLA transformer with a built-in pulse forming line, a main switch and an accurate trigger unit. Among them, the power supply provides electric energy to units such as the control unit, the energy storage unit and the precise trigger unit. The control unit completes the timing triggering, status monitoring, energy supplement, logic management, emergency management, fault detection and other functions of the whole system. The control unit is composed of existing FPGA and peripheral circuits, including A / D and D / A interfaces, optical fiber Interface, etc., the energy storage unit completes the storage of electric energy and the first level of energy compression, the TESLA transformer with built-in pulse forming line plays the role of pulse boosting and energy transmission, the main switch completes the second level of energy compression, and the...

Embodiment 2

[0038] On the basis of Embodiment 1, a diode is added, such as image 3 and Figure 4 As shown, the diode 11 is arranged at the other end of the packaging shell 10, and the diode 11 is connected to the inner cylinder 7 of the pulse forming line. In this solution, the diode is the high-voltage and high-current pulse output port of the entire modulator.

[0039] For the pulse modulator described in Embodiment 1 and Embodiment 2, its typical output parameters are as follows Figure 5 As shown, the miniaturized high-voltage and high-current pulse modulator proposed by the present invention can produce a voltage ranging from 100,000 volts to 500,000 volts, and an electric power of about 1 GW to 5 GW (1 GW=10 9 watts) of electrical impulse. The electrical pulse width is between 2 nanoseconds and 50 nanoseconds (1 nanosecond = 10 -9 seconds). The working mode of the miniaturized high-voltage and high-current pulse modulator is a pulse train type, that is, a limited number of elec...
