In the context that data centers today prioritize efficiency and stability, HVDC rectifiers—as critical power conversion equipment—directly impact the power supply safety of data centers through their electrical performance and reliability. Leveraging our expertise in power electronics testing, Kewell has introduced a targeted test solution to ensure the performance and reliability of HVDC rectifiers.

Kewell’s test system enables real-time monitoring and analysis of key parameters of HVDC rectifiers such as input/output voltage, current, power factor, and harmonics. It accurately simulates various load conditions and grid fluctuations, testing the dynamic response of rectifiers under rated load, overloading, underloading, and other conditions. This is to verify that the rectifiers output stable voltage and reach the required conversion efficiency, so that they deliver high quality power to data centers.

The PSU (Power Supply Unit), as a key power component for servers, directly affects system stability and reliability. PSUs are usually used to provide stable DC power to key components within servers. They feature high efficiency, fast dynamic response, low ripple, overvoltage/overcurrent protection, etc., and are widely used in data centers, cloud computing platforms, network communications and other fields to ensure stable operation of the equipment under diverse operating conditions. For PSU testing in systems, Kewell offers a test solution that boasts high precision, fast dynamic response, and high reliability. The DC output side features high control accuracy and great dynamic regulation capability, simulating operating states under different load conditions. The input side, on the other hand, supports grid simulation at various voltage and frequency levels, as well as simulation of abnormal grid conditions, thereby validating PSU performance across application scenarios. Additionally, the solution includes communication testing, timing sequence, signal testing, etc., ensuring that PSUs operate safely and stably even under complex conditions, meeting the high demands for power supply equipment.
