With the wide application of pulsed power supply in material surface modification

sewage treatment and biomedicine

pulsed power supply is developing towards miniaturization

simple driving and stability. At present

since the solid-state pulse power signal needs to be isolated at high voltage

the system is complicated and bulky. In order to reduce the weight and volume of the system

a topology of a single-signal-driven solid-state pulsed generator is proposed. The turn-on and turn-off of the first-stage switch is controlled by a signal

and the gate capacitance of the remaining switches is charged[JP3] through the main capacitor

and then the remaining switches are triggered themselves. Finally

based on this topology

a 10-level single-signal-driven solid-state pulsed generator circuit is simulated in PSPICE. The results show that the DC charging source of the [JP]new circuit topology works at 800 V

the system output amplitude is about 8 kV

and the pulse width is about 200~800 ns pulsed voltage

which is of great significance for biomedical applications

tumor ablation and sewage treatment.
