High Voltage Pulser Ic

It is designed for portable medical ultrasound applications.

High voltage pulser ic.

The output voltage swings are 100 to 100v. Rise and fall times are less than 15ns while sourcing and sinking over 2 0. This high voltage pulse supply will generate pulses up to 30 kv. R2 should be selected to limit the maximum repetition rate to 20 hz.

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. These dual pulsers feature independent logic inputs independent high voltage pulser outputs with active clamps and independent high voltage supply inputs. As can be visualized in the shown high voltage arc generator circuit diagram it employs a standard transistor blocking oscillator configuration for.

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. Ql and q2 form a multivibrator in conjunction with peripheral components rl through r6 and ci c2 c3 c5 c6 and d2. 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. R9 adjusts the pulse repetition rate.

For the values shown the circuit voltage drop is 10 v for a 1 µs 10 a pulse. 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. A bank of 36 marx generators is used by sandia national laboratories to generate. Hv748 is a four channel monolithic high voltage high speed pulse generator.
