Presentation of Suitable Topologies to Create a Generic Ultrasonic Puls Generator for Nondestructive Flaw Detection (English)
Abstract [sv]

I detta examinationsarbetesrapport för högskoleingenjörsexamen inom Elektronik, presenteras en utredning för att svara på vad som skulle vara den mest generiska pulsgeneratorn för ultraljudstestning inom det klassiska intervallet 0.5 till 15 MHz. Det presenteras flera variabler i teorin, som påverkar en testsignal och varför det inte går att beräkna vad en generisk pulsgenerator bör åstadkomma. Denna rapport presenterar vilka pulsgeneratorer det finns och vad de mer högpresterande pulsgeneratorerna beskrivna i vetenskapliga forskningsresultat har presterat. Samt vilka tekniker som finns och varför vissa tekniker inte är lämpliga. Vid slutet av denna examinationsarbetesrapport presenteras, med hjälp av några antaganden om vad en generisk pulsgenerator behöver prestera, dras en slutsats om vilken av de föreslagna pulsgeneratorerna som är mest generisk.

Abstract [en]

This bachelor thesis, is a trial in answering what would be a generic pulse generator for ultrasonic testing in the classic test range of 0.5 to 15 MHz. It also goes through multiple variables that affects a test signal and why it really isn't possible to precalculate what a generical pulse generators should achive, in the theory chapter. This thesis also goes through what different types of pulse generators there is and what some of the more high performance pulse generators proposed in scientific articles have achieved and what techniques that have been used and why some techniques are not suitable. In the end of this thesis there is a trial with some assumptions about what a generical pulse generator should achieve, to come to a conclusion about which pulse generator from the proposed ones would be the best generical pulse generator to go with.
