High Voltage Pulser for NDE Air-Coupled Lamb Wave Ultrasonic System

This paper describes a high voltage pulser developed for an air-coupled ultrasonic array NDE system based on Lamb waves. Unlike the classical single pulse excitation circuits, this pulser is able to generate a bipolar return-to-zero square-wave burst signal up to plus or minus 250 V of amplitude. Th...
