Technology Overview: Principles and Advantages of Low-Frequency Wireless Power Transfer

Low-frequency wireless power transfer (LF-WPT) systems are gaining renewed attention in 2025 as industries seek robust, efficient, and safe solutions for contactless energy delivery. These systems typically operate in the frequency range of a few kilohertz up to several hundred kilohertz, leveraging the principles of magnetic induction or resonant coupling to transmit power across air gaps. The core technology involves primary and secondary coils, where alternating current in the transmitter coil generates a time-varying magnetic field, inducing a current in the receiver coil. This approach is fundamentally different from high-frequency or radio-frequency (RF) wireless power, offering unique advantages in specific applications.

One of the primary advantages of LF-WPT is its resilience to misalignment and environmental interference. The lower operating frequencies result in deeper magnetic field penetration and reduced sensitivity to obstacles such as water, metal, or biological tissue. This makes LF-WPT particularly suitable for industrial automation, medical implants, and underwater applications. For example, Texas Instruments and STMicroelectronics have both developed integrated circuits and reference designs supporting low-frequency inductive power transfer, targeting sectors where reliability and safety are paramount.

Another significant benefit is the enhanced safety profile. LF-WPT systems generate minimal electromagnetic interference (EMI) and comply more easily with international safety standards for human exposure to electromagnetic fields. This is crucial for applications in healthcare and public infrastructure. Companies like Würth Elektronik and TDK Corporation are actively supplying magnetic components and ferrite materials optimized for low-frequency operation, supporting the growing demand for safe and efficient wireless charging in medical and industrial devices.

Efficiency is also a key consideration. While high-frequency systems can achieve higher power densities, LF-WPT offers stable efficiency over varying distances and misalignments, which is essential for dynamic environments such as automated guided vehicles (AGVs) and rotating machinery. Daifuku Co., Ltd., a leader in material handling systems, has integrated LF-WPT into its AGV solutions to enable continuous, maintenance-free operation in warehouses and factories.

Looking ahead, the outlook for LF-WPT in 2025 and beyond is promising.

Competitive Technology Comparison: Low-Frequency vs. High-Frequency Systems

Low-frequency wireless power transfer (WPT) systems, typically operating in the range of a few kilohertz to several hundred kilohertz, continue to play a significant role in the wireless power landscape as of 2025. These systems are primarily based on inductive coupling, leveraging magnetic fields to transfer energy between coils. Their competitive position relative to high-frequency systems (operating in the megahertz range and above) is shaped by several technical and market-driven factors.

A key advantage of low-frequency WPT is its proven safety profile and electromagnetic compatibility. The lower operating frequencies result in reduced electromagnetic interference (EMI), making these systems suitable for applications in sensitive environments such as medical devices and implantable electronics. For example, Medtronic and Abbott have both integrated low-frequency wireless charging into their implantable medical devices, citing reliability and patient safety as primary drivers.

In the electric vehicle (EV) sector, low-frequency WPT is the foundation of most commercial wireless charging solutions. The SAE International J2954 standard, which governs wireless charging for light-duty EVs, specifies operation at frequencies between 85 kHz and 90 kHz. Major automotive suppliers such as WiTricity and Qualcomm (through its Halo technology) have developed systems adhering to these standards, enabling interoperability and safety in public and residential charging infrastructure.

However, low-frequency systems face limitations in terms of power transfer distance and coil alignment sensitivity. The efficiency of energy transfer drops significantly with misalignment or increased separation between transmitter and receiver coils. This has spurred ongoing research and incremental improvements in coil design and compensation topologies, with companies like TDK and Texas Instruments offering advanced components and reference designs to address these challenges.

Compared to high-frequency systems, which can achieve greater spatial freedom and support smaller receiver sizes (beneficial for consumer electronics and IoT devices), low-frequency WPT remains dominant in applications where safety, regulatory compliance, and high power levels are paramount. The next few years are expected to see continued coexistence of both approaches, with low-frequency systems maintaining a stronghold in automotive, industrial, and medical sectors, while high-frequency solutions expand in consumer and low-power markets.

As of 2025, the competitive landscape is defined by the maturity, safety, and standardization of low-frequency WPT, with leading industry players and standards bodies ensuring its relevance in critical applications, even as high-frequency alternatives gain traction in emerging use cases.

Regulatory Environment and Safety Standards (Referencing ieee.org)

The regulatory environment and safety standards for low-frequency wireless power transfer (WPT) systems are evolving rapidly as the technology matures and finds broader applications in sectors such as electric vehicle (EV) charging, industrial automation, and consumer electronics. In 2025, the focus remains on harmonizing international standards, ensuring electromagnetic compatibility (EMC), and addressing human exposure to electromagnetic fields (EMF).

A cornerstone of the regulatory framework is the work of the IEEE, which has developed and continues to update standards such as IEEE 802.11bb for wireless communications and, more pertinently, the IEEE 802.15.7m and IEEE 802.11p for vehicular environments. For WPT, the IEEE 802.11 standard family is less relevant than the IEEE 802.15.7 and the IEEE 802.11p, but the most significant is the IEEE Standard 802.15.7m-2018, which addresses optical wireless communications, and the IEEE 802.15.7-2011, which covers short-range wireless optical communication using visible light. However, for low-frequency WPT, the IEEE 802.15.7 is not directly applicable; instead, the IEEE 802.15.4 and the IEEE 802.15.6 standards, which focus on low-rate wireless personal area networks and body area networks, respectively, are more relevant. The IEEE 802.15.6 standard, in particular, addresses safety and EMC for devices operating in close proximity to the human body, a key concern for low-frequency WPT systems.

The IEEE has also published the IEEE C95.1-2019 standard, which sets limits for human exposure to electromagnetic fields from 0 Hz to 300 GHz. This standard is critical for manufacturers and system integrators, as it provides the baseline for safe operation of low-frequency WPT systems, especially in public and residential environments. Compliance with IEEE C95.1 is increasingly being mandated by regulatory bodies in North America, Europe, and Asia.

In parallel, the International Electrotechnical Commission (IEC) and the International Organization for Standardization (ISO) are collaborating on the IEC 61980 and ISO 19363 standards, which specifically address wireless power transfer for electric vehicles, including safety, EMC, and interoperability requirements. These standards are expected to see broader adoption and possible updates in the next few years as WPT deployment accelerates.
