Huawei’s Stockholm Digital Power Lab (Stockholm Research Center) is responsible for Digital Power Advanced Technology Research, Architecture Evolution Design.
As we all know, the trend of power supply is high density and high efficiency, and high frequency is an effective measure to achieve those goals. But when the frequency up to 1Mhz, the parasitic parameters (stray inductances and capacitance) will affect the normal function of the circuit, and the magnetic flux will also vary greatly, those will make the converter with high losses.
So we are looking for a topic as “Design and modeling of the parasitic parameters on optimized LLC resonant converter at >1Mhz”, though this thesis, you will be analysed the effects of parasitic parameters at >1Mhz switch frequency based on the LLC resonant converter, and also give out the improvement to offset the impacts, including meanly the optimization the shape of the Magnetics components design.
Essential Skills required :
- Be familiar with the working principles of the LLC resonant converter.
- Skillful in using circuit and magnetic simulation tools, such as: PSIM, COMSOL Multi-physics, MATLAB & Simulink, PLECS, etc.
