Planar transformer

Planar transformers are devices used to exact standards with precise electrical characteristics such as capacitance, output, and aspect ratio.[1] They are used in military and aerospace projects.

Planar transformers[2] are high frequency transformers used in isolated switchmode power supplies operating at high frequency. As opposed to conventional "wire-wound-on-a-bobbin" transformers, planar transformers usually contain winding turns made of thin copper sheets riveted together at the ends of turns in the case of high current windings, or windings etched on a PCB in a spiral form. As the current conductors are thin sheets of copper, the operating frequency is not limited by skin effect. As such, high power converters built with planar transformers can be designed to operate at relatively high switching frequencies, often 100 kHz or above. This reduces the size of required magnetic components and capacitors, thereby increasing power density.

Advantages over conventional counterparts
  • High power density
  • 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[3]
gollark: Except you're using it wrong, and it probably slows you a lot, and most stuff should support AES or it's broken, and it's not been updated since july.
gollark: Yes, that is also bad.
gollark: Then you should use a faster encryption library, and also go to a company which allows you to remove technical debt.
gollark: In that case I'd say you're doing it wrong. You can send a random bit of data, stick it in an associative array or whatever stupid thing it's called mapping it to whatever this secret is, and then API 2 can take the random data, and find the secret in that associative array.
gollark: Look, if the client can't read the data anyway, *you can just send and store random junk*.
