Why Data Center Power Systems Need Standard Magnetics

As global data center power demand is forecast to triple by 2030, the industry is facing unprecedented pressure to deliver more power in less space, with greater efficiency and speed. Designing power systems for high-density environments like hyperscale and colocation data centers means navigating constraints in footprint, thermal management, and procurement timelines — all while ensuring uncompromising reliability.

Yet for many power engineers, one component continues to slow progress: custom magnetics.

While semiconductors have long benefited from standardized, off-the-shelf solutions that accelerate development and reduce risk, magnetics have remained a largely bespoke world. Each application often demands a new inductor design, new thermal modeling, and long lead times. This slows projects and complicates scaling — especially in high-growth environments like data centers.

Introducing CPMLMAX: Standardized, Medium-Frequency Magnetics for data centers

CorePower Magnetics is changing the equation. The CPMLMAX family offers pre-characterized, high-current inductors built for the power stage in data center applications — including UPS systems, power factor correction (PFC) stages, and isolated DC/DC converters.

Designed to operate at medium frequencies (10–100 kHz) and handle 50–300A current levels, CPMLMAX inductors offer:

• Up to 30% volume reduction vs. traditional powder core designs

• Up to 47% lower thermal losses, improving system efficiency and cooling

• Simulation-ready models, reducing engineering overhead

• U.S.-based manufacturing, providing faster, more secure lead times

A Semiconductor-Level Shift in Accessibility

This brings a level of accessibility to magnetics that design teams have long expected from standardized semiconductors — now extended to high power, medium frequency inductors.

Rather than waiting weeks or months for a custom inductor, teams can now integrate proven, high-performance magnetic components into their design from day one. That means faster prototyping, more confident performance prediction, and ultimately a shorter path to deployment.

Standard Magnetics for Data Center Power

Ideal Applications for standard inductors in Data Centers:

• PFC stages for 3-phase AC/DC rectifiers

• Isolated DC/DC converters in UPS and backup systems
