High Voltage Pulser Circuit

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.

High voltage pulser circuit.

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. As can be visualized in the shown high voltage arc generator circuit diagram it employs a standard transistor blocking oscillator configuration for. For the values shown the circuit voltage drop is 10 v for a 1 µs 10 a pulse. 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.

An unconventional multivibrator circuit was developed to provide high saturation currents over a wide range of supply voltages. A high current pulse forming network pfn has been developed for applications to artificial solar wind generation. Ii is a type 1156 lamp used as a current limiter. 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.

Ql and q2 form a multivibrator in conjunction with peripheral components rl through r6 and ci c2 c3 c5 c6 and d2. For a 50 spl omega matched load the pulser produces extremely well defined repetitive high voltage pulses that are free from overshoot and ringing. High voltage is used in electrical power distribution in cathode ray tubes to generate x rays and particle beams to. 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.

This high voltage pulse supply will generate pulses up to 30 kv. 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. Rise and fall times are less than 15ns while sourcing and sinking over 2 0. In certain industries high voltage refers to voltage above a certain threshold.

May 24 2017 thesis examination committee. A marx generator is an electrical circuit first described by erwin otto marx in 1924. Equipment and conductors that carry high voltage warrant special safety requirements and procedures. A bank of 36 marx generators is used by sandia national laboratories to generate.

R2 should be selected to limit the maximum repetition rate to 20 hz. R9 adjusts the pulse repetition rate. The output voltage swings are 100 to 100v.
