On March 31, CIQTEK successfully hosted the "EPR Frontier Technology Application Seminar" at the CIQTEK Hefei Headquarters. The main takeaway from the event is clear: high-frequency and high-field electron paramagnetic resonance (EPR) technology is rapidly becoming the ultimate solution for unlocking the micro-mechanisms of complex systems. By bringing together top EPR experts from around the world, the seminar fostered deep international collaboration and showcased how our latest multi-band EPR instruments are directly solving real-world experimental challenges in biomedical science, materials chemistry, and quantum sensing.

Sparking Innovation in Complex System Analysis

Compared to standard frequency bands, high-frequency and high-field EPR offers incredibly high resolution and sensitivity. This allows researchers to accurately capture the fine structures, dynamic behaviors, and weak interactions of complex molecules. It is a core technological tool for anyone working with biological macromolecules or advanced materials.

Hosted by Professor Wang Yiping from Peking University, the event attracted numerous researchers and professionals dedicated to advancing EPR technology. Dr. Xu Kebiao, Vice President of CIQTEK, delivered the opening remarks to welcome the attendees.

In power supply circuits, transformers and inductors look similar and are often confused. However, they differ significantly in function, structure, and application. Understanding their differences helps ensure greater clarity and accuracy in product selection, production, and design.

Transformers are mainly used for voltage conversion and electrical isolation. Through electromagnetic induction, they achieve voltage step-up, step-down, or signal isolation. A transformer has at least two sets of windings: primary and secondary.It converts between electrical and magnetic energy via a magnetic core.

They are widely used in chargers, power adapters, LED drivers, and other equipment. We commonly utilise frame series such as EE, EF, ER, and PQ, most of which are paired with high frequency electronic transformer bobbins.

Inductors are designed for energy storage, filtering, and current stabilization, without changing voltage. They usually have only one winding and use self-induction to resist current changes and suppress noise interference.Common structures include drum core inductors and toroidal inductors. They are widely used as power filter inductors and Encapsulated Series Common mode choke in anti-interference circuits.

In short:Transformers provide voltage transformation and isolation.Inductors provide energy storage and filtering.

Transformers require two windings and a closed magnetic circuit, while inductors usually use a single winding with more flexible magnetic paths.

In electronic equipment, they often work together to ensure stable power supply. Distinguishing their functions and structures helps avoid selection errors and improve product reliability.

Transformers are indispensable core components in electronic equipment and power transmission. Many people wonder why transformers are divided into high-frequency and low-frequency types. The answer is simple: differences in operating frequency determine their distinct structures and applications. Let’s explain this in plain terms.

The fundamental difference lies in operating frequency.Low-frequency transformers are designed for mains frequencies, typically 50Hz or 60Hz—the standard frequency for household and industrial power. Examples include the EE19 Consumer Electronics Power Control Transformer.

High-frequency transformers operate at much higher frequencies, ranging from several kHz to several MHz, commonly used in compact electronic devices, such as the EI13 LED power supply driver transformer.

Different frequencies require completely different core materials.Low-frequency transformers use silicon steel sheets for their cores. Laminated silicon steel reduces heat loss but results in larger size, heavier weight, and higher copper and iron consumption.High-frequency transformers use ferrite cores (often paired with EE or EI bobbins). Similar to ceramic in texture, ferrite supports high-frequency operation and prevents overheating.

Size and applications are also clearly distinguishable.At the same power rating, high-frequency transformers can be several to over ten times smaller than low-frequency ones—this is why phone chargers and LED drivers are compact and lightweight.Low-frequency transformers are mainly used for mains voltage conversion, audio equipment, and industrial control, such as traditional power adapters and machine tool control transformers.

In short:Low-frequency，Works at mains frequency, bulky and durable.High-frequency: Compact and efficient, ideal for electronic devices.Understanding this makes selection much easier.
