In high-performance power electronics, transformer design plays a key role. At Leibao, we focus on developing EE series power transformers that achieve low leakage inductance and high efficiency. This balance improves power delivery, reduces heat loss, and enhances system stability.
Optimized Core Structure Minimizes Leakage
The core structure greatly affects magnetic performance. Our EE series uses high-permeability ferrite cores, which ensure uniform magnetic flux distribution and significantly reduce magnetic leakage. Furthermore, the compact and symmetrical layout minimizes unwanted field paths, which enhances magnetic coupling.
Moreover, by selecting the right core size for each power level, we avoid flux saturation. This contributes to both stability and efficiency. Our engineers carefully match the core material and shape to each use case.
Precision Winding Reduces Parasitics
Winding layout is critical to leakage control. At Leibao, we use layered and interleaved winding techniques. This approach places primary and secondary coils closer together. Hence, magnetic coupling is stronger, and leakage is lower.
In addition, we apply automated winding equipment. This process maintains consistent spacing and tension. As a result, the coil geometry remains stable over time. Fewer parasitic effects mean better power transfer and less energy loss.
High-Efficiency Through Material and Design
Efficiency is not just a function of winding. We also use low-loss ferrite cores that reduce eddy current formation. These cores perform well at high frequencies, keeping thermal losses low.
Meanwhile, we coat our windings with high-temperature insulation. This material resists breakdown, even during prolonged use. Therefore, less energy is lost to heat, and the overall efficiency improves.
Further, we match the turns ratio and wire gauge precisely. This ensures minimal resistance and optimal voltage transfer. Together, these decisions lead to transformers that operate above 90% efficiency in typical use cases.
Controlled Leakage Enhances Circuit Performance
While low leakage is key, controlled inductance can be useful. For some applications, like flyback converters, a specific leakage level is needed. We tailor our designs accordingly.
This ability to fine-tune makes our EE series suitable for many topologies. Whether used in SMPS, LED drivers, or DC-DC converters, performance remains stable and efficient.
Reliability Built into Every Unit
To maintain long service life, we perform 100% testing on each transformer. Tests include:
- Inductance and leakage measurements
- Hi-pot dielectric strength tests
- Load and temperature rise validation
All units comply with RoHS and international safety standards. This ensures consistent quality for both domestic and export markets.
Conclusion
Our EE series power transformers combine precision engineering with quality materials. Through optimized core design, automated winding, and rigorous testing, we achieve low leakage inductance and high efficiency.
These advantages make our transformers ideal for today’s compact, high-performance power systems. If you seek custom solutions for demanding applications, Leibao is your trusted partner.
