会社ブログについて Supply and Recycling of Infineon REF-8KW-HFHD-PSU: An 8 kW High-Density Power Supply Solution Designed Specifically for AI Data Centers

Mingjiada Electronics Supplies and Recycles Infineon REF-8KW-HFHD-PSU: The Benchmark for High-Power-Density Power Supplies Empowering AI Data Centers

With the explosive growth in demand for artificial intelligence (AI) computing power, data centers and high-performance servers are facing unprecedented pressure on power supply. How to increase power output without adding rack space, while maintaining extremely high energy efficiency, has become a core challenge for the industry.

As a professional electronic component supply chain service provider, Mingjiada Electronics now supplies the Infineon REF-8KW-HFHD-PSU evaluation board to global customers and offers high-value buyback services for used units. This solution is an 8-kilowatt (8 kW) high-power-density, high-frequency switching power supply (PSU) reference design specifically engineered for next-generation AI accelerator cards and high-end servers.

I. Core Product Overview: Why Choose the REF-8KW-HFHD-PSU?

The Infineon REF-8KW-HFHD-PSU is a groundbreaking power supply reference design platform. It is not merely an evaluation board, but a complete solution addressing the challenges of achieving Titanium-level energy efficiency standards and managing power consumption in high-computing-performance applications.

This design leverages wide bandgap (WBG) technology—specifically the combination of Infineon’s proprietary CoolGaN™ gallium nitride (GaN) and CoolMOS™—to achieve power densities and switching frequencies that are difficult to attain with traditional silicon-based solutions.

Key Technical Specifications:

Input Voltage: Supports a wide range of global AC inputs (90–265 V AC) and high-voltage DC (HVDC) inputs, making it suitable for data centers in various regions.

Output Power: Continuous output capacity of up to 8,000 W, meeting the power supply requirements of multi-GPU/CPU clusters.

Power Density: A breakthrough level of > 100 W/in³, significantly saving rack space.

Conversion Efficiency: Peak efficiency exceeds 98%, significantly reducing data center cooling losses (PUE).

Topology: Utilizes a bridge-less totem-pole PFC combined with a full-bridge LLC resonant converter, paired with digital signal processing (DSP) to achieve high-frequency soft switching.

II. Application Scenarios: AI Data Centers and High-End Servers

During AI training and inference processes, the instantaneous power consumption of GPUs (such as NVIDIA H100/B200) or TPUs fluctuates dramatically. The REF-8KW-HFHD-PSU evaluation board is optimized for such dynamic loads:

Powering AI accelerator card clusters: Provides stable 48V or 12V bus voltages to handle large current spikes.

Hyperscale Data Centers: Helps engineers pre-validate power modules for next-generation Open Compute Project (OCP) standards.

Edge Computing and Enterprise-Grade Storage: Provides redundant and efficient power conversion within limited space.

III. Mingjiada Electronics’ Business Advantages: Dual-Drive Model of Supply + Recycling

1. Stable Supply and Technical Support

As a well-known component distributor in the industry, Mingjiada Electronics maintains a long-term stock of genuine REF-8KW-HFHD-PSU units.
