Driven by the exponential growth in AI computing demand, data centers and AI servers are undergoing a fundamental architectural transformation. As the core computing engine, GPUs have evolved from consuming several hundred watts to several kilowatts, with peak currents approaching 1,000 A per device. This trend is reshaping server thermal design and power distribution strategies while redefining the performance requirements of the Voltage Regulator Module (VRM) located adjacent to the GPU.

1. Industry Shift: AI Compute Is Redefining the Power Shelf Generative AI applications are rapidly penetrating all industries, driving exponential growth in AI computing demand. As a result, data center power architectures are undergoing significant transformation. Rack-level power is increasing to the megawatt (MW) level, while DC output voltages are evolving from traditional 12V and 48V systems toward ±400V and even 800V high-voltage designs. At the same time, AI workloads introduce highly dynamic and frequent power fluctuations, creating major challenges for conventional power architectures.

As 5G-Advanced continues to evolve and future 6G research advances, communication equipment is moving toward higher integration, lower power consumption, smaller form factors, and greater reliability. From communication modules, small-cell base station boards, and RF front ends to IoT terminals and power management modules, an increasing number of communication electronic products require precise power supply validation during both R&D and production stages.

With the rapid growth of AI computing and cloud infrastructure, data centers and high-density server clusters are placing increasingly stringent requirements on power continuity and system reliability. AI servers typically operate under high-load, high-power-density conditions. Any interruption in the primary power supply, even for a brief moment, can lead to interrupted computing tasks, critical data loss, and potentially system-wide failures.

As new energy vehicles continue to evolve toward higher-voltage and platform-based architectures, 400V/800V battery systems have become a key direction in vehicle electrical system development. While high-voltage platforms improve charging efficiency, reduce system losses, and enhance overall vehicle performance, they also place higher demands on the electrical stability of core components such as battery packs, DC/DC converters, and onboard chargers (OBCs).

1. Automotive Wiring Harness Testing Requirements: From Basic Continuity to Long-Term Reliability Verification With the rapid development of new energy vehicles, intelligent driving, and vehicle electronic/electrical architectures, automotive wiring harnesses are no longer just simple electrical connection components, but the key “neural network” throughout the entire vehicle for power supply, signal transmission, and system control.
