This thesis investigates a Printed Circuit Board embedded air core inductor at5 MHz switching frequency for two different prototypes 200 W-􀀀 5 A/ 250 nH and300 W -10 A/150 nH. The toroid structure has been used, as they have weaker external magnetic field compared to solenoid and spiral structure, hence, toroid structurehas less Electromagnetic Interference (EMI) issues. This research focuses on thermalmanagement of the proposed inductor for high current up to 10 A. The temperaturerise remains in the maximum range of 40°C without using a heat sink. Furthermore,finite element analysis was used to predict the temperature rise, resistance and inductance value. Then, hardware for these prototypes was implemented to verify simulated results. Hardware was also tested for filtering purpose of H bridge converter.To make a high performance inductor, an optimized design with 300 W-􀀀18 A/ 50 nHand with lower resistance was also proposed and same experiments were performed.In this design, 4 oz copper was used to reduce DC resistance and temperature rise.For 18 A current, the temperature rise also stays below 40°C.Therefore, proposed prototypes offer many benefits, such as higher efficiency, better filtering capability and lower manufacturing cost, can be brought in future high frequency converters by reducing the size of the passive elements.
