    [Measurement Example of the Influence of Air-Gaps] Figure 2-3 shows a B-H curve of a 0.35 ×3.0 ferrite slab. The blue curve shows the measurement of a B Coil with the hole size of 32.5 [mm ]. The yellow curve shows the measurement of a B Coil with the hole size of 82.5 [mm This shows how the saturation magnetic flux density and amplitude permeability change due to the influence of the...

    each other, if each measurement device is ideally tuned. For example, it is implausible that a sample that shows the highest core loss with one type of measurement device shows the lowest core loss with another type of device. In order to conduct accurate measurement, it is important to use a testing device with high measurement accuracy.

  • Page 17: Measurement Principles

    ■ 2.5 Measurement principles Fundamentally, this instrument employs vertical single-yoke type, magnetizing current (MC) method-based single sheet testing. The biggest drawback of a conventional MC method-based SST has been the inclusion of the measuring yoke-related core loss in the core loss of a sample. In other words, a conventional MC method- based SST measures the properties of a soft magnetic composite material core that is made up of 2 materials: the sample itself, and the yoke.
  • Page 18 Therefore, H (4). Magnetic flux density B inside a single sheet is ∫ V (5). A conventional MC method-based SST is equivalent to measuring the iron loss P per unit volume of a single . (Whenever “iron loss” is indicated hereafter, it mean iron loss per unit volume.) sheet from this H and B Because iron loss P is determined by dividing the area of the B-H curve by the cycle of the excitation signal,...
  • Page 19 Since the excitation current sent through the excitation coil of the measuring yoke is the same for the 1st and 2nd measurements; B derived in the 2nd measurement is, in fact, the magnetic flux density of the magnetic field strength H in the measuring yoke from the 1st measurement.
  • Page 20 In conclusion, by substituting H of formula (12) into the first term of formula (7), (13), ∫ H the actual iron loss of only the single sheet P can be calculated. Yoke Comp. comes into effect when Yoke Comp. is Enabled, as explained in 4.15. When Yoke Comp. is Disabled, testing is completed after the 1st measurement.
