Abstract The paper mainly studies a kind multi-electrode type triggered vacuum switch (TVS) and its trigger characteristics. The research first indicated that the trigger delay time was mainly decided by conduction delay time of TVS. And the increase of amplitude and steepness of triggered current can decrease the trigger delay time and its jitter. In the pulse transformer direct trigger mode, by reducing the leakage inductance of transformer, increasing the charging voltage or capacitance of trigger circuit capacitor could decrease conduction delay time and its jitter. But the trigger capacitance could not be continuously enlarged for a limitation of trigger energy with the capacitance keeping rise. The conduction delay time can be decreased to about 4μs. And the shortcoming of direct trigger mode is the large jitter and an easy-arc-extinguished phenomenon brought from a small triggered current for none infinite small leakage inductance. Two other kinds of trigger circuits were designed and discussed on the base of pulse transformer direct trigger mode: ① Matching a continuous-flow current circuit to pulse transformer trigger circuit. The trigger current could be enlarged and uninterrupted by the discharge of capacitor in continuous-flow current circuit. In this mode, the trigger current could increase to magnitude of kA and conduction delay time decreased to 2～4μs. And amplitude and steepness of trigger current is limited by the influencing of stay parameters in complex circuit. ② Improved circuit based on pulse transformer trigger circuit. By directly paralleling a capacitor between the trigger electrode and cathode, the conduction delay time could be hold on within 1μs stably with a small jitter. At last, the choice of maximum and minimum value of paralleled capacitor was then identified by theoretical analysis and experimental study of trigger characteristics of TVS. A more reliable and accurate trigger mode could be achieved by installing a series air gap between paralleled capacitor and trigger electrode to increase the trigger energy by a rising of capacitor charging voltage if the trigger voltage is small.
