多相DC-DC变换器中功率MOSFET选型与相数优化设计方法

This article presents a design methodology of sizing power mosfet switches with optimized phase counts to enhance the efficiency profile over a wide load range in multiphase dc–dc converters. In the conventional approach, identical sizes of all phases exhibit a large variation in power efficiency, especially over a wide load range. In the proposed method, power efficiency is improved in the entire...
