Super high current inductors-new energy storage devices more efficient and energy-efficient

Energy storage is an important supporting facility for the large-scale development of new energy. With the support of national policies, new types of energy storage represented by electrochemical energy storage such as lithium battery energy storage, hydrogen (ammonia) energy storage, and thermal (cold) energy storage have become important directions for the development of the energy storage industry due to their short construction period, simple and flexible site selection, and strong regulation ability. According to Wood Mackenzie’s prediction, the annual compound growth rate of global electrochemical energy storage installed capacity will reach 31% in the next 10 years, and the installed capacity is expected to reach 741GWh by 2030. As a major country in the installation of electrochemical pure energy storage and a pioneer in the energy revolution, China’s cumulative installed capacity of electrochemical energy storage will have a compound annual growth rate of 70.5% in the next five years.

At present, energy storage is widely used in fields such as power systems, new energy vehicles, industrial control, communication base stations, and data centers. Among them, large industrial and commercial users are the main users, therefore, the electronic circuits of energy storage equipment mainly adopt high-power design schemes.

As an important component in energy storage circuits, inductors need to withstand both high transient current saturation and long-term sustained high current to maintain surface low-temperature rise. Therefore, in high-power scheme design, the inductor must have electrical performance such as high saturation current, low loss, and low temperature rise. In addition, structural design optimization is also a key consideration in the design of high current inductors, such as improving the power density of the inductor through a more compact design structure and reducing the surface temperature rise of the inductor with a larger heat dissipation area. Inductors with high power density, smaller size, and compact design will be the demand trend

To meet the application needs of inductors in the energy storage field, we launched the different series of super high current inductors with extremely high DC bias capability, low loss, and high efficiency.

We adopts the metal magnetic powder core material design independently , which has extremely low magnetic core loss and excellent soft saturation characteristics, and can withstand higher transient peak currents to maintain stable electrical performance. The coil is wound with flat wire, increasing the effective cross-sectional area. The utilization rate of the magnetic core winding window is over 90%, which can provide extremely low DC resistance under compact size conditions and maintain the low-temperature rise effect of the product surface by enduring large currents for a long time.
The inductance range is 1.2 μ H~22.0 μ H. The DCR is only 0.25m Ω, with a maximum saturation current of 150A. It can operate for a long time in high temperature environments and maintain stable inductance and DC bias capability. At present, it has passed AEC-Q200 testing certification and has high reliability. The product operates in a temperature range of -55 ℃ to+150 ℃ (including coil heating), suitable for various harsh application environments.
The ultra high current inductors is suitable for the design of voltage regulator modules (VRMs) and high-power DC-DC converters in high current applications, effectively improving the conversion efficiency of power systems. In addition to new energy storage equipment, it is also widely used in fields such as automotive electronics, high-power power supplies, industrial control, and audio systems.

We have 20 years of experience in developing power inductors and is a leader in flat wire high current inductor technology in the industry. The magnetic powder core material is independently developed and can provide diversified choices in material preparation and production according to user needs. The product has a high degree of customization, short customization cycle, and fast speed.
