Abstract [sv]

The aim of our Thesis-project is to construct a DC/DC step-up converter which transforms 5 V up to about 1000 V. It will be used in a mobile equipment for measuring x-ray activity in physical experiments and in medical equipment. The specification has strong demands on the function and physical size. Our construction contains of a fly-back transformer, a switch-regulator, a power-regulator, a switch-transistor. The input power is stabilised by the power-regulator and chopped by pulse-width-modulating in the switch-regulator and then transformed. The output power is rectified and flattened by the capacitors and a diode. The power level is controlled by the switch-transistor, which adjust it according to the load. The whole process can be supervised by a microprocessor with an analogue signal from the converter.
