Tailored Transformers & Magnetic Elements for Energy Storage App

Custom Magnetic Components for Energy Storage Systems

Energy storage systems rely on power-electronic circuits to convert, control and manage electrical energy between batteries, power conversion systems and connected equipment.

Transformers, inductors and reactors are important magnetic components within these systems, supporting functions such as power conversion, electrical isolation, filtering, energy storage and current control.

Guangzhou KATOY Electronics Co., Ltd. develops and manufactures custom magnetic components for energy storage, renewable energy and industrial power-electronics applications.

Transformers for Power Conversion

In power conversion systems, transformers may be used for voltage conversion and electrical isolation.

Depending on the circuit topology and operating requirements, KATOY can develop:

• High-frequency transformers
• Low-frequency transformers
• Toroidal transformers
• Single-phase and three-phase transformers
• Other custom transformer designs

For high-frequency power conversion applications, transformer design typically considers switching frequency, input and output voltage, power level, insulation, temperature rise and mechanical dimensions.

Inductors and Reactors for Energy Storage Applications

Inductors and reactors are also widely used in power-electronic systems for functions such as:

• EMI filtering
• Current smoothing
• Energy storage
• Ripple reduction
• Harmonic control
• Power conversion

Important design parameters include inductance, rated current, operating frequency, magnetic core material, saturation characteristics, winding structure and thermal performance.

KATOY can develop custom inductors and reactors according to specific electrical and mechanical requirements.

Engineering and Customization

Energy storage equipment varies significantly in topology, power level, switching frequency, cooling conditions and installation structure.

For this reason, magnetic components often need to be customized for individual projects.

KATOY supports:

• Magnetic core selection
• Winding design
• Insulation design
• Thermal considerations
• Mechanical integration
• Sample development
• Testing and validation
• Recurring batch production

Customers can provide electrical parameters, dimensions, insulation requirements and application conditions for engineering evaluation.

KATOY Manufacturing Capability

Founded in 2004, Guangzhou KATOY Electronics focuses on electronic transformers and high-reliability magnetic components for industrial applications.

With more than 5,000 m² of manufacturing facilities, approximately 300 employees and an experienced engineering and R&D team, KATOY supports custom development, OEM/ODM projects and recurring manufacturing.

In addition to energy storage, KATOY magnetic components are used in welding equipment, professional audio, industrial power supplies, industrial automation, medical equipment and test instruments.

Supporting the Growing Energy Storage Industry

As energy storage and renewable-energy systems continue to develop, power-electronic equipment is placing greater demands on magnetic components in terms of power density, thermal performance, insulation and reliability.

KATOY will continue expanding its capabilities in energy storage, industrial power supplies and other power-electronics applications while supporting customers with customized transformer, inductor and reactor solutions.
