A tesla transformer with parallel magnetic circuit

Abstract

The invention provides a Tesla transformer with shunt-wound magnetic circuits. The Tesla transformer comprises an inner magnetic core (1), a secondary coil (4), a primary coil (3), an outer magnetic core (2), capacitors (5) and switches (6). The outer magnetic core (2) is formed by a plurality of outer magnetic core blocks, gaps are reserved between the outer magnetic core blocks, and the primary coil (3) is led out in a bi-wire mode and connects the capacitors (5) with the switches (6) to form a discharge loop. By two different means, a series-wound loop and a shunt-wound loop are formed in an integrated mode, and reliability and long-time stable operation capacity of the Tesla transformer are improved.

Description

technical field [0001] The invention belongs to the field of pulse power and relates to a Tesla transformer with parallel magnetic circuits. Background technique [0002] The Tesla transformer is a common high-voltage generating device. Its circuit is composed of two LC loops with magnetic coupling. The energy on the primary capacitor is coupled and oscillated by the two LC loops, and transferred to the secondary load capacitor to increase its voltage. . In the field of pulsed power technology, Tesla transformers (such as figure 1 , figure 2 (shown) is charging the pulse forming line. At this time, the primary coil (3) and secondary coil (4) of the Tesla transformer are embedded inside the coaxial pulse forming line, and are composed of the inner magnetic core (1) and the outer magnetic core (2). The open-circuit magnetic core of the Tesla transformer improves the energy efficiency of the Tesla transformer and shortens the time for the line voltage to reach the maximum v...

Problems solved by technology

If it is necessary to further increase the voltage to the megavolt level, one method is to increase the number of turns of the secondary coil, and the other method is to increase the primary voltage. Increasing the number of turns of the secondary coil will lead to a decrease in the insulation capacity of the secondary coil and increase the primary voltage The technical indicators of the primary circuit discharge switch must be improved. Both methods currently have technical limitations and cannot meet the long-term stable operation of Tesla transformers.
