四开关Buck-Boost变换器的准峰值电流控制策略

With the rapid increase of power consumption in data centers, the 48 V power delivery architecture is introduced, where a two-stage dc–dc power conversion solution is commonly adopted. Four-switch buck–boost (FSBB), as a topology with both voltage step-up and step-down capabilities, is very suitable for implementation as a front-end preregulation module. In this article, the quasi-peak current con...
