Simulating a DC Rectifier Without Compromise

Testing data center power infrastructure requires accurately simulating the high-voltage DC bus typically produced by an AC-to-DC rectifier (260–400 Vdc). Simulating a DC rectifier involves input and load testing using regenerative electronic load acting as a load emulator and can be programmed to have dynamic load conditions to test the rectifier. These tools replicate the rectifier’s dynamic behavior, enabling verification of system response to startup conditions, load transients, and fault events such as overvoltage, undervoltage, and overcurrent.

To assess energy efficiency and resilience, regenerative supplies source and sink power while returning unused energy to the grid. Rack-level configurations provide scalable, high-density rectifier bus emulation, supporting a single power supply unit (PSU) and full-system validation. Integrated software further automates test sequences, programs transient profiles, and monitors stability, ensuring datacenter equipment meets efficiency, reliability, and compliance requirements under varying operating conditions.

DC Rectifier Simulation Solution

Simulating a DC rectifier in a data center requires realistic source and load conditions, automation, and precision. The Keysight EL4900 Series Regenerative Electronic Loads applies constant current, constant resistance, constant power, and constant voltage profiles, executes rapid load changes, and supports long-duration cycling while returning energy to the grid. The Keysight automated power software suite enables start-up, efficiency, transient, and protection testing, including fault scenarios. Together, these tools provide an automated, repeatable, and energy-efficient rectifier simulation solution.
