Abstract
This application proposes a magnetic coupling coil optimization method. The method comprises: calculating an equivalent magnetic permeability of a magnetic coupling coil based on an air gap length of the magnetic coupling coil; calculating an effective cross-sectional area of the magnetic coupling coil based on the equivalent magnetic permeability and the power of the magnetic coupling coil; calculating a number of turns of the secondary winding of the magnetic coupling coil based on the effective cross-sectional area and the equivalent magnetic permeability; optimizing the magnetic coupling coil based on the number of turns of the secondary winding. The present application can reasonably configure the parameters of the magnetic coupling coil, effectively acquire energy from the power grid to provide stable power for detection or communication equipment in the power grid, and make the magnetic coupling coil more reliable while meeting the power demand.
