In the high-voltage technology during high-voltage tests it is very often necessary to trigger systems that is at a high potential, at least several kilovolts. A fairly common solution is the use of a three-electrode spark gap construction triggered by the command system, among others due to low construction costs and the possibility of brake-down voltage regulation in a wide range. However, always the problem of the triggering system ocures, due to the fact that it may operate at high potential. That causes the problem of galvanic isolation between the testing system and the control system. Construction The overriding goal in design process of the highvoltage triggering system was to develop a construction characterized by repeatability and a short self-time. The next step was to achieve as small dimensions as possible of the designing device and good energy efficiency. Very important, from the controlling device point of view, was also to ensure the maintenance of galvanic isolation between the control system and the trigger. The assumed goals were achieved by building an electronic triggering system based on the basic topology of flyback converters [1]. However, in this case, instead of the rectifier the ends of the secondary winding (L2) are connected to the auxiliary electrode and one of the main electrodes (Fig. 2). This solution was chosen due to the small number of necessary elements, which is associated with small dimensions of the entire device. The galvanic isolation between the control system and the trigger was implemented [...]
