Have you ever considered that the fast chargers we use every day, the home‑based new‑energy vehicle charging stations, and even the electric cars on the road all rely on a tiny “power heart” at their core—namely, power inductors? And the key factor determining the performance of these power inductors is the magnetic core.

The monoclonal antibody‑based DC‑blocking magnetic core independently developed by Anyang Jiayou has now entered stable mass production. Its key performance metrics are comparable to those of similar products from leading international brands, while offering a distinct advantage in overall cost of ownership.

What is Monoclonal antibody–resistant DC magnetic core To understand the value of single‑phase DC‑blocking magnetic cores, we first need to examine their application scenarios. As industries such as new energy, fast charging, industrial control, and 5G communications continue to grow rapidly, power electronic devices are increasingly trending toward “miniaturization, higher power, and greater efficiency.” Consequently, the demands on power inductors are rising: they must not only withstand larger DC bias currents but also maintain stable permeability, resist magnetic saturation, and at the same time achieve smaller form factors and lower losses.

Traditional ferrite cores tend to saturate under high DC currents, causing a sharp drop in inductance and making it difficult to meet the demands of high‑power applications. Meanwhile, commonly used air‑gap cores suffer from issues such as poor inductance accuracy, elevated operating noise, and relatively high losses. The product developed by Anyang Jiayou… The monolithic anti‑DC magnetic core is a novel type of core manufactured using a custom nanocrystalline processing technique. Leveraging a proprietary material formulation and an integrated molding process, the magnetic core inherently exhibits excellent DC‑saturation resistance, eliminating the need for an additional air gap. Under high‑DC‑current conditions, it maintains stable inductance output, effectively addressing the various operational challenges associated with conventional magnetic cores.

In short: Under the same power‑design requirements, inductors built with Anyang Jiayou’s single‑pole DC‑blocking magnetic cores can reduce volume by more than 30%, cut losses by 20%, and boost overall system efficiency by at least 5%, thereby meeting the growing demands of today’s high‑power‑density devices.

AnYang Jiayou has departed from conventional industry practices of air-gap compensation and multi‑piece splicing, leveraging a fully integrated production line that incorporates independently controlled vacuum annealing, precision transverse magnetic heat treatment, and monolithic winding‑and‑forming processes. By reengineering the microstructure and tailoring proprietary heat‑treatment protocols, it has developed an all‑in‑one, single‑layer, DC‑resistant nanocrystalline magnetic core, achieving multiple performance enhancements across three key dimensions: bias‑magnetization resistance, loss control, and thermal stability.

Compared with conventional soft magnetic materials, Anyang Jiayou’s proprietary single‑layer DC‑resistant magnetic core offers multiple application advantages under mainstream operating conditions in the new‑energy sector:

✅ Excellent bias magnetic immunity : It is compatible with normal DC superimposition operating conditions; under high-current operation, it avoids deep magnetic saturation, thereby mitigating core bias‑induced heating and performance degradation.

✅ Mid-to-high frequency low-loss performance : Compatible with the mainstream 20–100 kHz operating frequency range of new energy systems, with controllable temperature rise under DC bias conditions, helping to improve overall system efficiency.

✅ High power density advantage High magnetic flux density supports the miniaturization of equipment design, reducing both the overall device footprint and associated material costs.

✅ Stable output under multiple operating conditions : Wide-temperature-range tolerance, vibration resistance, and low operating noise, balancing dynamic response accuracy with long-term operational reliability.

✅ More cost‑effective across the entire lifecycle. : No redundant structural design is required in the early stage, and subsequent operations and maintenance as well as replacement frequency are lower, resulting in a lower long-term total cost of ownership compared to conventional magnetic‑core solutions.

Leveraging its superior overall performance, Jiayou’s monoclonal antibody‑based DC‑resistant nanocrystalline magnetic core is compatible with a wide range of core equipment in next‑generation power systems, effectively addressing key challenges in engineering applications.

👉 Grid‑level solid‑state transformers (SSTs), addressing the operational challenges of mid‑frequency DAB topologies—namely, voltage‑current imbalance and frequent transient DC bias—can stably withstand DC bias under high‑frequency conditions without requiring additional hardware compensation circuits. This simplifies the overall system design, enhancing the operational stability and safety margin of grid‑side equipment.

👉 The high‑ and low‑voltage energy storage PCS filter inductor is compatible with residential, commercial & industrial, and high‑voltage energy storage applications across all scenarios. It is tailored to the operational characteristics of bidirectional charging and discharging in energy storage systems and frequent load fluctuations, effectively mitigating temperature rise and additional losses caused by DC bias, thereby enhancing overall system energy conversion efficiency. It is also suitable for 1500V high‑voltage energy storage systems.

👉 Automotive power equipment and precision industrial‑control power supplies are engineered to meet the demanding operating conditions of vehicle‑mounted systems—characterized by compact installation spaces, significant temperature fluctuations, and frequent current surges. Leveraging their compact form factor, wide‑temperature stability, bias‑magnetism resistance, and low‑noise performance, these solutions seamlessly integrate with high‑end automotive applications such as on‑board SSTs, onboard chargers, and high‑precision filtering devices.
