How does a high-voltage switch work?
S is a series of high-voltage switch components, R1 is a current-limiting protection resistor, R2 is a load resistor, and C is an energy storage capacitor. It works as follows: the high-voltage direct current (DC) power supply is charged to the high-voltage capacitor C after a protection resistor R1.

Finally, a high-voltage solid-state switch is developed based on the SiC MOSFET series connections, whose output pulse width is adjustable from 20 to 300 μs, frequency is adjustable from 1 Hz to 3 kHz, the maximum output voltage can reach 57 kV (1 Hz), and the overcurrent protection time is about 1 μs.
What is a high-voltage MEMS plasma switch?
A high-voltage MEMS plasma switch is developed to control a buck converter transferring the energy between the buffer and the final reservoir. The switch control law is provided with an automatic narrow hysteresis loop, in order to hold the voltage across the buffer capacitor always oscillating between two high voltage levels.

Also, an overcurrent protection scheme is proposed in this paper to enhance the reliability of the switch in failure in a short circuit. Finally, a prototype high-voltage switch component with a maximum output voltage of 57 kV is built, which can turn off the short-circuit current within 1 μs. Figure 1 shows the circuit schematic.
How do you store electrical energy in a low-voltage circuit?
To store the generated electrical energy in order to power low-voltage electronics, a specific conditioning circuit should include an AC-to-DC converter and a DC stabilization module. Basic conditioning strategies are based on full-wave (FW) or half-wave (HW) diode-bridge rectifiers, which charge a large capacitor to a DC voltage.
