Compare the magnetic core energy storage expression (9) with the total energy storage expression (14), it can be seen that the total energy increases by z-multiple after the addition of air gap, from Eqs. (16), (17) indicate almost all the energy is stored in the air gap, and the energy of magnetic devices expands and increases.
Magnetic core and air gap energy storage On the basis of reasonable energy storage, it is necessary to open an air gap on the magnetic core material to avoid inductance saturation, especially to avoid deep saturation. As shown in Fig. 1, an air gap Lg is opened on the magnetic core material.
However, the larger the air gap is, the effective permeability of the magnetic core will decrease, and the magnetic flux density will decrease under the same current. Therefore, increasing air gap to expand energy storage is limited, Next, control variable method is used to analysis. 4.
Compare equations (36), (37), that the energy stored in the magnetic core is only 3.03% of the total energy, and the ratio of the energy stored in the magnetic core to the energy stored in the air gap is 1:32. It is verified that most energy is stored in the air gap during energy conversion of magnetic devices.
According to the air gap dilution factor discussed in ampere-turns unchanged, magnetic induction intensity is constant, inductance constant several cases related to energy storage relationship, finally concluded that the magnetic device energy storage distribution relations.
