Custom High-Frequency Transformers
KATOY designs and manufactures custom high-frequency transformers for switching power supplies, converters, inverters and other industrial power-electronic applications. Designs are developed around converter topology, switching frequency, electrical requirements, insulation, thermal conditions, winding construction, dimensions and mounting constraints.
Designed Around the Actual Power-Conversion Circuit
A high-frequency transformer cannot be selected by power rating alone. Its magnetic and electrical design depends on the switching frequency, converter topology, input and output conditions, core material and geometry, flux density, winding arrangement, insulation requirements and thermal limits.
KATOY develops custom ferrite-core transformers based on the customer’s circuit requirements, drawings or reference samples. The objective is to match the transformer construction to the actual operating conditions rather than force the application into a fixed catalog design.
- Converter topology: evaluated together with electrical requirements and switching conditions.
- Operating frequency: considered when selecting magnetic structure and winding design.
- Insulation: developed according to voltage, isolation and application requirements.
- Thermal performance: considered together with losses, materials, dimensions and installation conditions.
- Mechanical construction: customized for PCB mounting, wire leads, pins, dimensions and equipment layout.
High-Frequency Transformer Constructions
KATOY manufactures high-frequency transformers in a range of ferrite-core, winding, lead and mounting configurations. The products below illustrate representative custom constructions rather than fixed standard models.
EE, EFD, ER and PQ High-Frequency Transformers
Different ferrite-core geometries provide different winding windows, magnetic paths, profiles and mechanical packaging options. Core selection is made according to the actual transformer design rather than by geometry alone.
Common ferrite-core geometry suitable for a wide range of customized winding and mounting arrangements.
Low-profile ferrite-core structure considered where transformer height is an important mechanical constraint.
Ferrite-core structure available for customized high-frequency transformer designs and packaging needs.
Compact ferrite-core geometry used where magnetic, winding and mechanical requirements suit the structure.
Information Used for High-Frequency Transformer Development
Providing complete circuit and operating information allows the transformer design to be evaluated against the actual application instead of relying on approximate catalog substitution.
High-Frequency Transformers for Power Electronics
Custom high-frequency transformers can be developed for different switching power-conversion applications according to the circuit, electrical specifications and mechanical requirements.
From Technical Review to Recurring Production
As a custom high-frequency transformer manufacturer, KATOY supports industrial OEM projects from requirement review and magnetic design through prototype development, validation and recurring production.
Verification Based on Product Requirements
High-frequency transformer verification should correspond to the electrical and insulation requirements of the design. KATOY performs production and electrical inspection according to defined product specifications and quality procedures.
Test requirements are established according to the actual transformer design and customer specification rather than applying one identical test profile to every product.
- Electrical parameter inspection
- Winding and connection verification
- Insulation-related testing as specified
- Visual and dimensional inspection
- Production process and quality control
High-Frequency Transformer Questions
These answers address common technical and sourcing questions about custom high-frequency transformer development.
What information is needed to design a custom high-frequency transformer?
Useful information includes the converter topology, switching frequency, input and output requirements, power conditions, winding configuration, insulation requirements, dimensional limits, mounting method and application information. A schematic, drawing or reference sample can also support technical evaluation.
How is the ferrite core selected for a high-frequency transformer?
Core selection depends on factors including operating frequency, transformer topology, power requirements, magnetic flux conditions, winding space, thermal limits and mechanical constraints. EE, EFD, ER and PQ are examples of available core geometries, but the suitable structure depends on the complete design.
Can KATOY manufacture high-frequency transformers from customer drawings or samples?
Yes. Projects can be evaluated from electrical specifications, drawings, circuit information or reference samples. Additional technical information may be required before prototype development depending on the application.
Are high-frequency transformers available for SMPS and inverter applications?
KATOY develops custom high-frequency transformers for switching power supplies, inverters and other industrial power-conversion applications. The transformer must be designed around the specific circuit and operating conditions rather than selected only by application name.
Can prototype development be followed by recurring production?
KATOY supports projects from technical review and prototype development through validation and recurring manufacturing. Production requirements are established after the design and sample are confirmed.
