Nowadays every electronic equipment contains some sort of energy conversion, which means that a mains connected power supply consists of a bridge rectifier, and depending on the application further conversion is needed to generate the required electrical quantity. These power electronic devices turn on and off rapidly causing disturbances in form of current harmonics. DC/DC converters offer the characteristics of making any switching load appear as resistive loads, which makes them suitable for Power Factor Correction (PFC). To achieve the desired output voltage level a control loop is needed.
In my final project I investigated the boost, buck-boost, bridgeless buck-boost and flyback converter topologies. First I gave a general overview of the theoretical background of operation of the various topologies. After that I simulated every mentioned topologies completed with control loop using MATLAB.
After simulating the systems in MATLAB I also designed a printed circuit board (PCB) for one chosen converter topology using Kicad. I presented a detailed description of the designing steps and basic designing rules.
