Embodiment 1
[0045] see figure 1 , figure 2 , forming a linear typical Marx generator based on a magnetic switch, including a pulse source with adjustable frequency pulse width; a magnetic pulse compression circuit; forming a linear Marx generator based on a magnetic switch; matching load four parts, among which the linear Marx generator The structure is:
[0046] N-level PFLs are charged in parallel, and the shielding layer (skin) and core port at one end of each level of PFL are connected to the circuit through a pair of coupled inductors, and the pair of coupled inductors is connected to the PFL with the same name, N-level PFL and its coupled inductor The relevant parameters of the pair should be exactly the same, and the direction of the same-named end of the coupled inductor on each side of the N-level PFL circuit should be consistent. The connection method of all levels of PFLs discharged in series through magnetic switches is as follows: the charging current inflow terminal of th...

[0053] Figure 5 Shown is the circuit topology diagram of the two-stage forming line charging and discharging port isolation type Marx generator. Compared with the circuit topology of the two-stage forming line type Marx generator based on magnetic switches, the connection method of the magnetic switch is changed: PFL 5 with PFL 6 The first end is connected to the circuit through a coupled inductor, and the tail end is connected in series through a magnetic switch to discharge to a matching load.
[0054] The connection method of the magnetic switch at the end is as follows: the wire core at the end of the first-stage PFL is grounded through MS7, and the end wire sheath of the n-stage PFL is connected to the end wire core of the n+1-stage PFL through a magnetic switch. The small inductance of the coupling inductance during the charging process is equivalent to a short circuit, the large inductance of the magnetic switch is equivalent to an open circuit, and the Marx generator...

[0057] Figure 6 Shown is the circuit topology of the two-stage magnetic switch parallel charging type Marx generator. Compared with the circuit topology of the two-stage magnetic switch-based linear Marx generator, the positions of the magnetic switch and the PFL are reversed. Magnetic switch MS through a coupled inductance 10 -MS 12 Perform parallel charging.
[0058] The advantage of the two-stage magnetic switch parallel charging type Marx generator is that the original circuit topology works as the magnetic switch MS 10 -MS 12 Impedance and PFL 9 -PFL 10 The impedance is relatively small, and the MS 10 -MS 12 A large current will flow, causing the current flowing through each coupled inductor to be different, so that the magnetic flux is unbalanced, and the PFL 9 -PFL 10 Charging consistency becomes poor. Figure 6 When a large current flows through the magnetic switch, the topological structure will improve the magnetic flux balance of the coupled inductor, the...
