EE / EF cores are used as power shapes in electric circuits such as inductors and transformers. They are an ideal material to use at low frequencies where large inductances are required. The cores offer the advantage of material permeability and have a uniform cross-sectional area. They do not have any gaps, so the leakage is very low. This is why the toroidal core windings are commonly used in current and instrument transformers.

We are an acclaimed name engaged in offering our precious clients a superior quality range of Soft Ferrite Cores. The offered cores are widely used in transformers and conductors. These cores are sourced from most authentic vendors in the market and are manufactured with the help of finest grade material and contemporary machines in compliance with set industry norms. Clients can avail these cores from us at affordable rate.

The other matter for core selection is core geometry and it is possible to find pot, E shape, toroid cores and the others in manufacturer catalogues depending on

their applications. Pot cores, when assembled are nearly surrounded the wound bobbin and this aids in shielding the coil from picking up EMI from outside

sources. Double slab and RM cores are also similar to pot cores but are designed to minimize board space, providing at least a 40 % savings in the mounting

area. EP Cores are round centre-post cubical shapes which enclose the coil completely except for the printed circuit board terminals. PQ cores are designed especially for switched mode power supplies. The design provides an optimized ratio of volume to the winding area and surface area. E cores are less expensive than pot cores and have the advantages of simple bobbin winding plus easy to assemble. Also, E cores can be mounted in different directions, and if desired, they provide a low profile.

EC, ETD, EER and ER shapes are a cross between E cores and pot cores. Like E cores, they provide a wide opening on each side. Toroid cores are economical to manufacture; hence, they are the least costly of all comparable core shapes. Since no bobbin is required, accessory and assembly costs are nil, but winding is done on toroidal winding machines. Ferrite geometries offer a wide selection in shapes and sizes.

To choose a core for power applications the parameters in Table 1 can be used and evaluated [7,9, 17, 19]. Different shapes of Ferrite core types areshown MnZn Ferrite E Core EE55/28/25

E cores are more advantageous in terms of core, coil and winding prices and easy to use, also with cross-sectional area and window spacing of different sizes. E cores have a double flux path which reduces their dimensions and this allows for small footprint and easy installation on printed circuits. E cores air gap can be adjusted, but the fringe fluxes formed in cores with air gap lead to flow losses and eddy current (Eddy) losses on winding wires as shown in Figure 3 (a). Therefore, Kool Mµ E powder cores with an equal air gap as shown in Figure 3 (b) are more preferred. The 10.500 gauss saturation level of the

Kool Mµ E powder cores provides higher energy storage capability that they can be achieved with the air gap ferrite E-cores, which means a smaller core size [19, 20]
