Planar transformers are devices used to exact standards with precise electrical characteristics such as capacitance, output, and aspect ratio.[1] They are used to carry out military and aerospace projects.
Advantages over conventional counterparts
Bulleted list item
Significantly reduced height (low profile)
Greater surface area, resulting in improved
heat dissipation capability.
Greater magnetic cross-section area, enabling
fewer turns
Smaller winding area
Winding structure facilitates interleaving
Lower leakage inductance resulting from
fewer turns and interleaved windings
Less AC winding resistance
Excellent reproducibility, enabled by winding structure [2]
