Design of Controller for High Voltage Switching (English)
Abstract [sv]

I det här examensarbetet har hårdvara och mjukvara för att styra switchningen av en högspänning till en röntgendetektor utvecklats. Examensarbetet har utförts på uppdrag av företaget XCounter som utvecklar avancerade röntgendetektorer. Resultatet av arbetet är ett kretskort som monteras i en av företagets röntgendetektorer. Kretskortet och mjukvarans funktionalitet är att switcha en högspänning samt reglera fem dioder enligt ett mönster som är ställbart i mjukvaran. Mönstret ställs utifrån en synksignal som kommer från detektorn. Timingen av händelserna är kritisk. Denna rapport beskriver utvecklingen av detta kretskort och den tillhörande mjukvaran. Från planering av komponenter till simulering av konstruktionen till själva utvecklingen.

Abstract [en]

In this thesis the hardware and software has been developed for controlling the switching of a high voltage to an X-ray detector. This thesis has been done on the behalf of the company XCounter that develops advanced X-ray detectors. The result of this work is a circuit board that is mounted in one of XCounters X-ray detectors. The circuit board and software functionality is to switch the high voltage and regulate the five diodes according to a pattern that is adjustable in the software. The pattern is adjustable in relation to a sync signal coming from the detector. The timing of the events is critical. This report describes the development of this circuit board and associated software. From the planning of components to the simulation of the design to the actual development.
