E and EF ferrite cores are used in power transformers and low signal applications. These cores can be supplied with different air gaps, and AL values. They are made of different ferrite materials, mainly power materials. Two pieces of ferrite cores with or without air gap are set. Inductance factor AL depends on the size of the air gap in the middle leg.

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. Transformer Magnet

The main component in inductance design is the core structure where to be used for magnetic flux flow is provided. Air cores, iron cores, ferrite and powder cores are known inductance cores. Ferrite and powder cores are preferred for high switching frequency power converters having less loses and saturation. Ferrite cores are cheaper and have low power losses at higher switching frequencies but the flux level is lower. These cores are obtained from Mn-Zn and Ni-Zn alloys and have F, P, R, K types depending on the alloy’s ratios . Also, the air gap in cores makes it preferable against the saturation.
Powder cores have an air gap dispersed in the material due to the nature of the material from which they are produced, and this feature is ideal for switching rectifiers. In addition to a soft saturation characteristic, this feature provides a lot of design convenience, such as small core volume, overcurrent protection, low heat, and powder cores provide high levels of DA magnetic force characteristics without saturation.

The energy harvesting from renewables, and also using it more efficient is an important topic for the scientific researchers today. The power electronics circuits and devices are the main parts for renewable energy applications and also to be storable the energy efficiently. The scientific researchers are focused on design and control of the converters, and also increases the efficiency of the power electronic circuit’s components.

One of the main components of the power electronics circuits is inductances. The electrical energy is stored in the inductance temporarily in switch mode power converters. The inductance; which is like the heart in a human which storage and pump the blood, the storage the energy temporarily and pumps the energy from the source to load in switch mode converters, and supply continuously and the circuit current on the load .
The energy efficiency of converters depends of course on the inductance efficiency. So a well-designed inductance is very important for the converter in continuous mode operation and continues the current to flow uninterrupted. The inductance value determines how to operate the converter under load
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.
