Analyzing high voltage converter : Parameteridentification, modelling and simulation of high frequency converter (English)
Abstract [sv]

Detta arbete har genom experiment, simuleringar, beräkningar och tester undersökt en högspänningskrafttransformator för höga frekvenser. Med hjälp av en steganalys identifierades parasitelemet i kraftomvandlaren. En transformator modell och en likriktarmodell kunde tas fram. Genom att använda LT-spice kunde resultatet valideras.

Abstract [en]

Analyzing parasitic elements of devices is important because they cause power losses. Minimizing the losses leads to less raw material consumption for devices, which in turn leads to reduced environmental impact. In the project a pulse generator is constructed which can provide low voltages pulses. Using the pulse generator, the parasitic components of the power converter with it’s transformer are identified and analyzed. After the parasitic analysis, a model for the transducer was developed. The system's U-I characteristics were simulated and analyzed at different switching pulse widths. In order to validate the results of the survey, the project has compared the physical measurements with simulation. The result shows good consistency.
