Resum
This paper describes the design and development of a high-power high-resolution pulser designed especially for air-coupled ultrasonic nondestructive evaluation applications requiring high material penetration capability. The pulser can deliver up to 800 V in a spike excitation type pulse to appropriate low/medium frequency transducers. Moreover, the pulser operates in three different modes: single pulse, double pulse (pulse cancellation technique), and external reference signal, where the last t...
