Overview
Traditional data center architectures rely on several power conversion steps to provide direct current (DC) power to IT equipment. Hitachi Energy’s Active Front End (AFE) technology converts power at the medium-voltage level, reducing conversion stages and improving power-supply efficiency.
The converters support advanced 800 VDC architectures while facilitating the connection of DC-generating power sources, such as battery energy storage systems (BESS), hydrogen fuel cells, and solar photovoltaic power.
Designed for high-density data centers
Fast response and advanced active power management help meet the operational requirements of modern computing environments while supporting reliable power delivery.
Improve efficiency and reliability
By reducing conversion stages, AFE technology can improve end-to-end efficiency by up to five percent, ensuring better energy utilization.
Reduce complexity
AFE power convertersintegrate with complementary Hitachi Energy data center solutions to strengthen power resilience, reduce outage risk, and ensure continuous operations while supporting the transition to a carbon-negative business future.
Benefits
Scalable architecture
Our AFE converters support racks that range from 100 kW to more than 1 MW using the same data center power infrastructure, allowing seamless expansion as power requirements increase.
Reduced copper requirements
Compared to traditional architectures, 800 VDC enables significant reductions in current, copper usage, and thermal losses across the data center backbone.
Improved reliability
Centralizing power conversion improves system reliability while simplifying fault detection and serviceability.
