[JAC113] Power Transmission Analysis of a Wireless Power Transfer System with Opposing Cores
By changing the position of the opposing core, the power transmission efficiency was examined whether the efficiency reduction due to positional deviation is within the allowable range.
Vertical Distance vs. Power Transmission Efficiency
Magnetic flux density distributions with varied vertical distance between the primary and secondary sides are shown in Fig. 1, and the vertical distance versus power transmission efficiency curve is shown in Fig. 2. The leakage flux increases and the magnetic flux inside the secondary side core falls with greater vertical distance, as indicated in Fig. 1. Approximately 80% of maximum efficiency can be achieved when the vertical distance is 2 mm, as indicated in Fig. 2. The efficiency falls basically linearly because the reduction in flux linkage in the secondary coil is caused simply by the increase of the vertical distance.
