Inductor Secret: Working Principle of Minimal Inductance

With the development of semiconductor materials, the third generation of gallium nitride and silicon carbide semiconductors have gradually entered people's vision, continuously reducing the size of chargers. A multi port charger that supports simultaneous charging of multiple devices has greatly facilitated our lives. Low-power mobile power sources are also gradually exiting the market, and more and more high-power fast charging charging batteries are entering the market. The size is not significantly different from ordinary charging batteries, but they support high-power input and output.
