AC-Coupled vs. DC-Coupled

Growing applications for battery storage mean the optimal system design may not be the most obvious. Jakir Hossain and Mujtaba Abdelwahab of Storlytics Energy Storage present a simulation-based comparison of AC vs. DC coupling showing how realistic dispatch modeling rather than generic assumptions fundamentally changes BESS sizing, levelized cost of electricity (LCOE) outcomes and architecture selection.

California-based power electronics maker Enphase announced it developed a new solid state tranformer technology for next-generation data center power infrastructure, including emerging higher-voltage direct current (DC) rack power architectures for AI workloads. Instead of using one large, centralized converter, Enphase Energy’s IQ Solid State Transformer (IQ SST) converts power in data centers to 800 V …
