2kW 4-phase interleaved buck converter reference design with coupled inductors
TIDM-02022
概述
The significant growth of data center power consumption led an increase in demand for highly efficient DC/DC brick converters with high power density. Isolated topologies are prevalent but control is difficult. A multiphase synchronous buck topology with coupled inductors have better load transient performance and are easier to control compared to isolated topologies like inductor-inductor-capacitor (LLC). This reference design shows the control (Voltage mode) of power stage using a C2000™ microcontroller.
