AI server racks are pulling more current from less predictable grids than the data center industry has ever had to plan for. As AI and hyperscale builds push into areas with thinner grid infrastructure, server power supplies must ride through voltage sags, surges, and outages that would have been rare a decade ago. The ITIC […]
What is AC Circuit Emulation? Modern energy systems demand smarter tools. Whether you’re testing EV inverters, V2G systems, solar inverters, or smart grid equipment, your test environment should reflect the complexity of real-world electrical behavior. That’s where AC electronic load circuit emulation mode comes in. Circuit emulation allows an electronic load to replicate the behavior […]
The AI data center boom is rewriting the rules of power delivery. Racks that once drew 15-20 kW now routinely exceed 100 kW — some GPU racks already draw 120-140 kW — and 1 MW rack designs have already been shown at industry events. Every stage of that power path — from the utility feed […]
White Paper Executive Summary Unintentional islanding poses safety risks, including hazards to utility workers, equipment damage, and service disruptions. Anti-islanding protection is essential for distributed energy resources (DERs) like solar inverters, battery storage, and Vehicle-to-Grid (V2G) systems in which energy is pushed back onto the grid. This white paper provides a comprehensive overview of anti-islanding […]
AC Power Hardware in the Loop (PHIL) Grid Connected Test Applications What is Power-Hardware-in the-Loop? Power-Hardware-in-the-Loop (PHIL) allows users to perform realistic closed loop tests without the need for testing on a real system. PHIL provides a real-time simulation environment through the exchange of low voltage/current signals that can be employed for the higher power […]
