Process Solution for Flat Transformer

Advantages of flat transformers

High current density

Small size

High efficiency

Good repeatability of parameters

Wide working frequency range

Wide working temperature range

Good insulation performance

Low leakage sensation

Good heat conduction

Low EMI radiation

The actual conductive wire of the planar transformer
Above are some planar conductors, therefore
High current density

The use of small magnetic cores can correspondingly reduce
Volume 

Efficiency can reach 98%~99%

Because the winding structure is fixed and easy to pre install
Process first, so the parameters are stable

The frequency can range from 50kHz to 2MHz

The working temperature ranges from -40 ℃ to 130 ℃

Flat transformers consist of conductive circuits and insulators
The edges overlap with each other to form a protective layer
Between the windings, at the beginning— Secondary and secondary
— Next timeUp to 4 kV insulation isolation between levels

About 0.2% of the primary inductance

Short distance of hot channel, low temperature rise

Good magnetic core shielding can reduce radiation
To very low 

Process characteristics of planar transformers

Thick copper from 2-6oz

Line width (coil) consistency

Copper thickness uniformity
