“…Before and after the breakpoint are the initial period and the stable period, respectively. The switching process is significantly affected by the variation of V DS , and similar results can be observed and explained in an electrically triggered field-distortion spark gap [19][20][21][22]. The switching ON capability exhibits a gradual decline with decreasing V DS , I DS cannot be switched ON when V DS decreases to 410 V. By contrast, the switching OFF capability becomes stronger as V DS decreases and weaker as V DS increases.…”

Since the physical and electrical properties of plasmas are similar to the semiconductordevice, the plasma devices are proposed to be good candidates for switching controlleddevices while applied in harsh environments. In the proposed paper, a microplasma devicewith dielectric barrier structure constructed with three electrodes (two driven electrodes andone trigger electrode) is fabricated, and the electrical characteristics of the proposed deviceare investigated in 2 kPa of argon. From the experimental results, a stable conducting currentis obtained through two driven electrodes in the device due to gas discharge, since thehysteresis characteristic of discharge plasmas (discharge is still maintained when drivenvoltage is below the breakdown voltage of the gas because of the existence of residual chargeparticles), the device can be switched from OFF to ON state through pre-discharge by a pulseapplied on the trigger electrode. While in the device ON, this trigger voltage attracts channelcharged particles to the surface of the dielectric layer, quenching the discharge plasma currentand the device can be switched from ON to OFF state. The trigger pulse that makes thedevice switch successfully is from single to continuous up to 80 kHz. The influence of pulseparameters on the switching process is also investigated, pulse amplitude and pulse width arefound to be important to whether the device can be switched ON or OFF, peak current afterswitched, and the response speed of switching ON current, however, these switchingparameters are barely affected by the rising and falling time of the pulse. The results aresignificant for the application of microplasma switching devices.

“…A four-electrode switch is a variant of the classic threeelectrode field-distortion switch [16][17][18]. In a three-electrode switch, the external electric pulse is applied to the disk-like middle electrode, and an overvoltage gap is constructed between the middle electrode and cathode (or anode).…”

This work investigates the pulsed breakdown processes and mechanisms of self-triggered pre-ionized switches with a four-electrode structure in nitrogen through ICCD (Intensified Charge Coupled Device) photographs. The diameter of the trigger plane hole mainly determines the switch’s electric field distribution. Two configurations with minimum and maximum trigger plane holes are adopted for comparison. In the switch with a minimum trigger plane hole, the maximum electric field distributes at the surfaces of the main electrodes. Though charged particles in the triggering spark channel cannot drift out, homogeneous discharges can be stimulated from both the cathode and anode surfaces through UV (ultraviolet) illumination. Two sub-gaps are likely to break down simultaneously. In the switch with a maximum trigger plane hole, the maximum electric field locates near the trigger electrodes. Discharges in both sub-gaps initiate from the trigger electrodes in the form of a positive or negative streamer. Due to lower breakdown voltage and electric field threshold for discharge initiation, the cathode side sub-gap breaks down first. The analysis of two extreme examples can be referenced in the future design and improvement of self-triggered four-electrode switches with different structures of trigger electrodes.
