Abstract(in English) | Recently, miniaturization of power supply is required along with miniaturization and high performance of electric and communication equipment. High frequency switching is effective for miniaturization of the power supply. This paper clarifies that the problems of the fabricated prototype synchronous back converter using GaN-HEMT and the fabricated Si based driver IC are long wire bonding and dead time generator using external capacitor. In addition, we propose strategies for solving the problems. As a result, efficiency of POL at 10 MHz and 30MHz were more than 90 % and 80 %, respectively when Li-ion battery is used as a power source. |
