The relentless pursuit of efficiency and miniaturization in modern electronics has placed high-frequency switching power supplies (SMPS) at the forefront of power management design.
At high frequencies, when the conductor thickness exceeds twice the skin depth, the internal current density decreases significantly, leading to a decrease in material utilization.
Due to its unique closed magnetic circuit structure, inductors have the advantages of low leakage flux and high efficiency in high-frequency applications, but the contradiction between their size and heat dissipation performance often becomes a design bot
The relentless demand for smaller, lighter, and more efficient power electronics has driven a significant shift from traditional wire-wound transformers to planar transformer technology.
In today's rapidly developing power electronics and new energy technologies, the contradiction between power conversion efficiency and device size is becoming increasingly prominent.
As a core magnetic component of high-frequency power electronic systems, the leakage inductance control of planar transformers directly affects system efficiency, electromagnetic compatibility, and device reliability.
