High Power Planar Transformer

A Planar Transformer is a modern type of power Transformer designed for high power density, low profile, and high efficiency applications. Unlike conventional wound Transformers, Planar Transformers use flat copper conductors and multilayer PCB windings, enabling superior thermal performance and repeatable electrical characteristics.

Ferrtx planar transformers are engineered for compact power systems where efficiency, reliability, and manufacturability are critical, making them ideal for advanced power electronics and high-frequency power conversion designs.

What Is a Planar Transformer?

What is a planar transformer?
A planar transformer integrates copper windings into PCB layers or flat copper sheets instead of traditional round wire windings. This structure significantly reduces leakage inductance, improves heat dissipation, and allows precise control of electrical parameters.

Compared with traditional Transformer designs, planar transformers offer:

• Lower profile and higher power density

• Improved thermal management

• Better consistency in mass production

• Optimized performance at high switching frequencies

Because of these advantages, planar transformers are widely adopted in modern Power Converter architectures.
