Musadiq, Muhammad
As we recognize that the number of people on earth is growing at an exponential rate, so does the energy demand, if producing power from wind and solar is contemplated, resources can be used to meet that demand. The purpose of this thesis is to design a converter that helps to integrate the renewables into the DC Microgrid smoothly and encounters the thermal issues on its own. To avoid these circumstances’ reliability of the power converters increased by reducing the temperature issues and the thermal variation which occurs due to changes in operating conditions and for this variable switching and variable inductance technique has been applied in the system. In this thesis, a system is built to perform the simulation concerning real environmental conditions. The system is consisting of a condition monitoring unit which will monitor failure indicators and there will be an active thermal control unit which will control the temperature of the converter with the help of switching techniques. The methodology has been applied for various switching frequencies for the power electronic DC-DC converter. The lifetime consumption outcome at 5kHz without controller 4.75928 x 10-96 and without controller 2.65298 x 10-95. The outcome at 10kHz without controller 4.75928 x 10-96 and with controller 1.75285 x 10-95. By analyzing the results, it can be concluded that the overall reliability of the converter is increasing with the increase in frequency.
