What is the topological principle of a five-stage stacking generator?

Finally, the topological principle is verified by experiments, and a prototype of the five-stage stacking prototype is built. With the charging voltage of 28 V, the generator can output pulse with a voltage amplitude of 10 kV and pulse width of 12 ns whose voltage gain is up to 357 times.

What is a switching power supply?

The switching power supply is used to supply power to the main circuit PCB. Figure 13 shows the waveform of the pulse voltage on the load. A 10-kV voltage pulse is generated using the 5-stage stacker with a pulse width and rise time of 12 and 4.2 ns, respectively.

How is a 10 kV voltage pulse generated?

A 10-kV voltage pulse is generated using the 5-stage stacker with a pulse width and rise time of 12 and 4.2 ns, respectively. Compared with the single-module experiment, the waveform effect after superposition has some changes. It can be seen that the pulse width and rise time are increased compared with the results of the single-module experiment.

How to measure higher voltages with a 6 kV probe?

To measure higher voltages with a 6 kV probe, we use two 250 Ω resistors in series as the load and measure it through voltage division. The switching power supply is used to supply power to the main circuit PCB. Figure 13 shows the waveform of the pulse voltage on the load.

How many kV is a PCs module?

The source drain voltage of the device is V ds = 1.2 kV, and 15 modules are used for each phase in series for 18 kV, meeting the insulation requirements of the 10 kV voltage level. The rated capacity of each module is 23.8 kW, and the rated through current is about 34 A, with a sufficient through current margin. Figure 15. PCS prototype.

What is the peak value of transient overvoltage at LVDC?

The peak value of transient overvoltage at the LVDC side is about 720 V and overshoot is about 0.02%, and the peak value of transient overcurrent at the LVDC side is about 480 A and overshoot is about 68.4%, which is within the allowable range. Under the condition of 20% rated power, the output current THDi is 3.31%, as shown in Figure 8. Figure 7.
