PCB Planar Transformer for Compact Power Electronics
A PCB Planar Transformer is a magnetic component designed to use planar winding structures, typically formed by copper traces on printed circuit boards or dedicated planar conductors. Compared with conventional wire-wound designs, planar transformer technology can support a low-profile construction and repeatable winding geometry, making it suitable for power electronics applications with strict space and assembly requirements.
Planar transformers are commonly considered for high-frequency isolated DC-DC converters, industrial power supplies, telecommunications equipment, and other compact power conversion systems. Their performance depends on factors such as winding layout, core geometry, operating frequency, leakage inductance, parasitic capacitance, thermal management, and insulation design.
HYL offers customized planar transformer solutions based on the customer's electrical and mechanical requirements. Design options can be evaluated according to the target PCB layout, input and output specifications, power rating, isolation requirements, mounting arrangement, and available space.
If you are developing a compact power supply or need a planar magnetic component for a specific converter design, share your PCB files, schematic, drawings, or technical specifications with HYL. Our team can help assess design feasibility and provide a tailored quotation.
With ultra-slim flat PCB layout design, this planar transformer delivers stable performance under high voltage and high power conditions. It is extensively adopted in automobiles, EVs, HEVs, charging stations and new energy storage devices.
Key attributes
1. high current density. The wires of planar transformer are planar conductors, so the current density is high.
2. high efficiency. Efficiency as high as 98%~99%.
3. low leakage inductance. About 0.2% of the primary inductance.
4. good heat conduction. Short hot aisle distance, low temperature rise.
5. low EMI radiation. Excellent core shielding keep radiation low.
6. small size. Use small magnetic core, reduce volume accordingly.
7. The parameter repeatabiltiy is good. Fixed winding structure, easy to pre-process, reduce stable parameters.
8. wide operating frequency range. From 50KHz to 2MHz.
9. wide operating temperature range. Form -40℃~130℃.
10. Good insulation. The planar transformer is composed of conductive circuits and insulating sheets overlapping each other, which ensure up to 4KV insulation between winding, primary-secondary & secondary-secondary.
