Abstract [eng] |
This final master's project is designed to analyze the characteristics of high-frequency voltage-boosting power supplies, to create a model of the converter with the help of computer equipment and to perform its computer research. Perform experiments with an experimental layout, setting its parameters to different operating modes. The literature analysis section discusses the main high-frequency pulse power supply topologies, their areas of application and operating principles. The causes of noise during their operation and ways to suppress or avoid it are reviewed. In the part of computer research, a model of a step-up converter is created. The influence of the circuit components on the generated electromagnetic noise, the influence of external parameters on the operating modes of the converter and the heating of the components are investigated. In the experimental part of the converter, tests are performed with the model of the step-up converter. The test is used to analyze the operating modes of the converter at different input and load parameters. The efficiency of the power supply when operating under different conditions is calculated. A study of the thermal properties of a circuit element is performed. |
