摘要: Plasma switch devices such as thyratrons, spark gaps, and ignitrons have enjoyed great success in closing-switch applications where high currents must be switched from voltage on short time scales with low forward-voltage drop. However, plasma are not usually considered repetitive fast opening switches. Although they can opened by commutation (or counterpulse techniques), requires significant power, recovery times generally long: ≳ 10 μs. Ideally, a is desired which perform both closing functions at speed repetition rates under low-power control, like hard-vacuum tube, but without the large drop thermionic-cathode current restrictions associated hard tubes.
