Abstract
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 ±250 V of amplitude. The system is composed of two 32 elements concave array with a resonant frequency of 800 kHz. To excite all the transducers an array of pulsers with small volume and weight to be able to place it close to the conca...
