R-type transformers are characterized by a uniquely shaped magnetic core. This design alters the magnetic field distribution path, resulting in an uneven magnetic field profile and endowing the inductor with distinctive electromagnetic properties. Thanks to the customizable core geometry, this product series is well suited for applications with specialized electromagnetic requirements. Its design approach encompasses thermal management, miniaturization, and customization.

An inverter is a DC-to-AC converter that transforms direct current into alternating current. Its core function is to convert electrical energy from DC to AC, thereby meeting the power requirements of various applications. It finds widespread use across numerous scenarios.

Toroidal transformers are constructed by winding silicon steel laminations into a continuous toroidal magnetic circuit, with the windings evenly wrapped around the core. They offer advantages such as high efficiency and energy savings, low operating noise, minimal vibration, low temperature rise, and a compact footprint. These transformers are widely used in high-fidelity audio equipment, medical electronic instruments, computer power supplies, industrial control current transformers, solar inverter systems, and other applications.

A high-frequency transformer is a power transformer that operates at frequencies above the intermediate frequency (10 kHz). Its operating principle is as follows: when an alternating current flows through the primary winding, the magnetic core generates an alternating magnetic flux, inducing a voltage or current in the secondary winding, thereby achieving transformations of voltage, current, and impedance. These transformers are widely used in high-frequency switching power supplies and high-frequency inverter power supplies.

Potting transformers are transformers in which the internal components are completely encapsulated and sealed with an insulating material. Their defining feature is the use of a potting process to encase the internal windings and parts, creating a robust, hermetic seal that effectively prevents the ingress of moisture, humidity, dust, and other external environmental factors, thereby averting short circuits or insulation failure. They are widely employed in humid, dusty, or corrosive environments.

EI low-frequency power transformers are the mainstream choice for low-frequency applications. Named after their E‑shaped and I‑shaped silicon steel laminations, they utilize electromagnetic induction to step up or step down mains‑frequency AC voltage while providing electrical isolation. With a simple structure and moderate cost, they have become the preferred solution for industrial power supply equipment, widely employed in industrial control systems and electronic devices.
