High Voltage Pulser Ic

This high voltage and high speed integrated circuit can also be used for piezoelectric capacitive or mems sensing in ultrasonic nondestructive detection and sonar ranger applications.

High voltage pulser ic.

Fast risetime pulses of 0 to 1000 v with currents up to 50 a can be generated by this simple low cost high. This high voltage pulse supply will generate pulses up to 30 kv. 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. Rise and fall times are less than 15ns while sourcing and sinking over 2 0.

These dual pulsers feature independent logic inputs independent high voltage pulser outputs with active clamps and independent high voltage supply inputs. The output voltage swings are 100 to 100v. A bank of 36 marx generators is used by sandia national laboratories to generate. The max4806 max4807 max4808 integrated circuits generate high voltage high frequency unipolar or bipolar pulses from low voltage logic inputs.

For the values shown the circuit voltage drop is 10 v for a 1 µs 10 a pulse. R2 should be selected to limit the maximum repetition rate to 20 hz. 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. Ii is a type 1156 lamp used as a current limiter.

Hv748 is a four channel monolithic high voltage high speed pulse generator. Ql and q2 form a multivibrator in conjunction with peripheral components rl through r6 and ci c2 c3 c5 c6 and d2. As can be visualized in the shown high voltage arc generator circuit diagram it employs a standard transistor blocking oscillator configuration for. 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.
