6. Design and Optimization of HF Transformers for High Power DC-DC Applications
Abstract : Increasing the operational frequency is the most common solution to achieve higherpower densities, since the weight and volume of the magnetic part, the bulkiestelement in power electronics converters, are then decreased. This solution is wellestablished in low power high frequency applications, while in the recent decade,the possibility of utilizing high frequency at higher power and voltage levels hasgenerated wide interest as well.

8. High Frequency (MHz) Planar Transformers for Next Generation Switch Mode Power Supplies
Abstract : Increasing the power density of power electronic converters while reducing or maintaining the same cost, offers a higher potential to meet the current trend inrelation to various power electronic applications. High power density converters can be achieved by increasing the switching frequency, due to which the bulkiest parts, such as transformer, inductors and the capacitor's size in the convertercircuit can be drastically reduced.
