Planar Transformer
High Power Density Planar Transformers, PCB Windings, Flat High-Frequency Power Magnetics
Planar Transformers, often termed PCB Transformers or Flat Magnetics, are specialized High-Frequency Power Transformers utilizing Printed Circuit Board (PCB) Windings. This advanced structure delivers Compact Form Factors, Superior Thermal Performance, and Precise Electrical Consistency, making them indispensable for modern High Power Density (HPD) and High-Efficiency Power Conversion applications.
By utilizing multi-layer PCB traces instead of conventional wire, Planar Transformers achieve Ultra-Low Leakage Inductance, Optimal Magnetic Coupling, and highly Precise Winding Geometry. The low-profile design naturally enhances Heat Dissipation (Thermal Management) and facilitates Automated Assembly, leading to superior performance Repeatability and stability in high-frequency power converter designs.
Superior Thermal Management & Maximized Power Density
The Low-Profile Structure combined with the large copper surface area of the PCB windings significantly enhances heat spreading and thermal management, allowing Planar Transformers to achieve Maximized Power Density in confined power supply architectures.
