“…Triggered vacuum switch (TVS) tubes, or 'sprytrons', have found a range of applications in highvoltage, high-current pulsed power circuits, offering a wide operating voltage range for the commutation of kilo-ampere peak currents, within a compact mechanical envelope [1][2][3][4][5]. The general arrangement of the three-electrode TVS device is shown in Figure 1 below.…”

The construction and physical operation of a miniature triggered vacuum switch (TVS) are described, including DC and pulsed pre-breakdown images associated with the surface-flashover initiation of the vacuum switch tube.Colour imaging of pre-breakdown phenomena within the surface-flashover trigger module of the switch envelope is presented, and its key features discussed in relation to the pre-breakdown phase of a high-voltage vacuum gap closing switch.Key operating parameters of a TVS device are then presented, and this performance reviewed in the context of fast-rising commutation of high-current pulses within the switch tube, quantifying the performance improvements obtained through the adoption of a doped trigger region.Finally the physical robustness of the TVS mechanical package is reviewed, along with its suitability for use in switching fast-rising current pulses into insensitive loads, and its application in aggressive environmental conditions.

“…A new concept was suggested in 1999 to evaluate the benefits of a hybrid approach to switching [7]. The concept was to take advantage of the relatively high current performance of the triggered vacuum switch during the main portion of the current transfer pulse but to add series andor parallel switches to assist with the turn-off function.…”

The size, weight, power rating, availability and reliability of electrical power systems are important for future weapons systems. Applications could include: advanced vehicles and systems; potential new weapons; and man-portable or alternative power. Over twenty R&D studies in pulsed power have been initiated by IAT for the U.S. Army over the last three years. Highlights of some developments in rotating machines and PFN components are described.
