Problems solved by technology

[0012] The technical problem to be solved by the present invention is to increase the inter-turn insulation of the secondary winding for the current Tesla-type pulse transformer with a high step-up ratio, which will cause the overall volume and weight of the transformer to double, which does not meet the requirements of the overall system. The problem of miniaturization and compactness requirements; and the insulation failure problem of breakdown between the primary winding and the secondary winding at the edge of the transformer in practical applications, which affects the stability of the continuous repeated frequency operation of the system, proposes a compact double-layer The secondary Tesla-type pulse transformer can not only realize the compactness and high step-up ratio of the Tesla transformer to the greatest extent, but also ensure the insulation reliability of the Tesla transformer when it operates repeatedly at high voltage.

Description

technical field [0001] The invention relates to a Tesla (Tesla) type pulse transformer, in particular to a compact double-level pulse transformer, which belongs to the field of high-power pulse drive sources. Background technique [0002] With the gradual deepening of the application of pulse power systems in military, industrial, and civilian fields, especially the continuous progress of vehicle-mounted, airborne, and ship-borne high-power microwave weapons, the requirements for modularization and miniaturization of the system continue to increase. Modularization is convenient for modularized transportation and maintenance, and the miniaturization of the system is in line with the current loading capacity of mobile equipment. At present, there are two main means of boosting the pulse power system, namely Marx generator and Tesla type pulse transformer. Tesla-type pulse transformers have the characteristics of no need for synchronous switches, compact structure, strong stab...
