Optimizing Intermediate Bus Converter Performance for High Power Systems

Technical Article Overview 

The shift to 48 V power distribution in modern data centers has created new requirements for intermediate bus converters. Quarter-brick power supplies must deliver high efficiency, strong transient performance, and high output power within a tightly constrained form factor.

This technical article from Analog Devices presents performance data for a quarter-brick power supply reference design optimized for 48 V data center architectures. The design delivers 2 kW output power, achieves 98.59% peak efficiency at 48 V input, and reaches 97.68% efficiency at full load for 54 V input.

The article reviews efficiency, power loss, transient response, thermal performance, startup behavior, and ripple characteristics to show how power density and reliability can be achieved together. Use this reference to evaluate design principles for high efficiency intermediate bus conversion in next-generation data center systems.
