Abstract: In today's fast-paced, information-driven world, data centers can offer high-speed, intricate capabilities on a larger scale owing to the ever-growing demand for networks and information systems. Because data centers process and transmit information, stability and reliability are important. Data center power supply architectures rely heavily on isolated bidirectional DC-DC converters to ensure safety and stability. For the smooth operation of a data center, the power supply must be reliable and uninterrupted. In this study, we summarize the basic principle, topology, switch conversion strategy, and control technology of the existing isolated bidirectional DC-DC converters. Subsequently, existing research results and problems with isolated bidirectional DC-DC converters are reviewed. Finally, future trends in the development of isolated bidirectional DC-DC converters for data centers are presented, which offer valuable insights for solving engineering obstacles and future research directions in the field.

Key words: Data centers, isolated bidirectional DC-DC converters, power electronics topology, control strategy
