Abstract

A new integrated inductor for a 2-phase interleaving buck converter is designed and built in this work. ZVS is achieved by sizing the inductor based on energy balance and introducing the k factor. A 4-leg magnetic core structure is proposed as the integrated inductor. By introducing the modified parameter αeff to iGSE method, the optimal switching frequency for core loss can be found, which is 2 MHz in this case. A highly compact prototype, featuring stacked PCB solution, with 16.2 × 19.2 × 6 mm3 size is built. Input voltage ranges from 6 V to 12 V and the converter is capable of delivering up to 10 A at 4 V output. Peak efficiency of 96 % is achieved.
