A high current pulse forming network pfn has been developed for applications to artificial solar wind generation.

High voltage pulser circuit.

May 24 2017 thesis examination committee. Ii is a type 1156 lamp used as a current limiter. This high voltage pulse supply will generate pulses up to 30 kv. It is switched by static induction thyristor sithy and is capable of generating pulsed current of 9 7 ka for a time duration of 1 ms.

Adaptive high voltage pulse signal generator circuit design a thesis presented by lixi tao to the faculty of the graduate college of the university of vermont in partial fulfillment of the requirements for the degree of master of science specializing in electrical engineering october 2017 defense date. Its purpose is to generate a high voltage pulse from a low voltage dc supply marx generators are used in high energy physics experiments as well as to simulate the effects of lightning on power line gear and aviation equipment. An unconventional multivibrator circuit was developed to provide high saturation currents over a wide range of supply voltages. Ql and q2 form a multivibrator in conjunction with peripheral components rl through r6 and ci c2 c3 c5 c6 and d2.

The high voltage pulser circuit shown in figure 1 utilizes supertex s complementary p and n channel transistors tc6320 driven by an md1213 to achieve excellent performance and efficiency with minimal components. Equipment and conductors that carry high voltage warrant special safety requirements and procedures. Using simple but powerful electronics concepts such as a mass produced schmitt trigger and integrated mosfet driver in novel circuit applications a simple 400 v 75 ns pulse generator pulser has been designed developed and tested. A bank of 36 marx generators is used by sandia national laboratories to generate.

For the values shown the circuit voltage drop is 10 v for a 1 µs 10 a pulse. High voltage is used in electrical power distribution in cathode ray tubes to generate x rays and particle beams to. In certain industries high voltage refers to voltage above a certain threshold. A marx generator is an electrical circuit first described by erwin otto marx in 1924.

R9 adjusts the pulse repetition rate. R2 should be selected to limit the maximum repetition rate to 20 hz. High voltage electricity refers to electric potential large enough to cause injury or damage. A simple high voltage generator circuit is explained here which can be used to step up any dc level to about 20 times or depending upon the transformer secondary rating.

Rise and fall times are less than 15ns while sourcing and sinking over 2 0. For a 50 spl omega matched load the pulser produces extremely well defined repetitive high voltage pulses that are free from overshoot and ringing. Duty or dwell is a few milliseconds and the high voltage pulse is generated at the end of the period when the circuit is broken and the field of t1 rapidly collapses trough the winding.
