Magnetic Powder

Powder cores are distributed air gap cores made from ferrous alloypowders for low losses at high frequencies. Small air gaps distributedevenly throughout the cores increase the amount of DC that can be passedthrough the winding before core saturation occurs. Molybdenumpermalloy powder (MPP) cores are excellent for low loss inductors such asswitching regulators and noise filters. High Flux, Sendust and Mega Flux cores are better choice for the powerfactor correction(PFC), switching regulator inductors, in-line noise filters,pulse and flyback transformers, and many other applications required forlow losses at high frequencies.

CSC’s advanced technologyenables to fulfill diverse needsof clients regarding soft magnetic powder cores.

Magnetic Powder Cores ::: 04

CSC manufactures four types of soft magnetic powder cores of the Molybdenum Permalloy (MPP), High Flux, Sendust andMega Flux , which are mainly used for inductors and transformers requiring the low losses and inductance stability underhigh DC bias conditions. The fully standardized production management under strict control from raw materials (nickel,iron, molybdenum, aluminum and silicon) enables CSC to guarantee stable quality in confidence to customers.

MPP Ni-Fe-Mo alloy powder cores are made from an alloy powder ofnickel, iron and molybdenum.MPP cores exhibit highly approved stability in temperature, inductance under high DCmagnetization or high DC Bias conditions. They offer the highest permeability among ourmaterials and the lowest core loss than any other core material. MPP cores are also consideredas a premium material for direct current output inductors for SMPS including high Q filter,Loading coil, EMI/RFI filter. Finished toroid cores are coated with a gray epoxy to providedielectric protection and extra physical strength.

HIGH FLUXNi-Fe alloy powder cores are made from an alloy powder of nickel and iron.The 15,000 Gauss saturation level of High Flux cores brings higher energy storage capabilityand more effective permeability than performance of gapped ferrite or powdered iron cores ofa size. Excellent DC bias characteristics and low core losses of High Flux cores offer not onlysize and number of winding turns reduction but also good magnetic properties. CSC High Fluxcores are excellent choices for applications such as PFC reactor, switching regulator inductor,in-line noise filter, pulse transformer, flyback transformer. Various shapes are availables.Finished toroid cores are coated with Khaki color.

SENDUSTFe-Si-Al alloy powder cores are made from an alloy powder of iron,silicon and aluminum.Near Zero magneto restriction makes Sendust cores ideal for eliminating audible noise in filterinductors. Core losses of Sendust core are significantly lower than those of powdered ironcore’s. Especially Sendust E shapes provide a higher energy storage capability than gappedFerrite E cores'. Gap losses and eddy current losses are minimized with Sendust E cores ascompared to Gapped Ferrite E shapes. Sendust cores would be smart choices in PFC circuit;major application is switching regulator inductor, In-line noise filter, pulse transformer andflyback transformer also. They are coated with black color.

MEGA FLUXFe-Si alloy powder cores cores are made from an alloy of iron and silicon.CSC has developed new magnetic alloy powder cores for the first time in the world under thename of Mega Flux . It is the sensational development in recent design, requiring a smallersize, higher current, higher energy storage capability. Mega Flux cores have higher fluxdensity of 16,000 Gauss than any other magnetic material, compared to 15,000Gauss for HighFlux cores and 10,000 Gauss for Sendust cores. Extremely good DC bias characteristics givethe best solution for high end applications such as buck/boost inductor for high power supplysystem, smoothing choke for inverter, reactor for electric vehicle. Mega Flux cores pressedwith no organic binder have significantly lower core losses than powdered iron cores and Fe-Sistrip cores. They also present the good thermal properties with no thermal aging effects.

Core Dimension Table(milimeters)



The inductance of a wound core at a given number of turns is calculated using the following formula.

L

L = inductance(μH)

μ = core permeability

N = number of turns

A = effective cross section area(cm2)

= mean magnetic path length(cm)

LN = Inductance at n turns(μH)

AL = nominal Inductance(nH/N2)

Magnetic Design Formulas

Inductance of Wound Core

Ampere’s law and Faraday’s law show the relations of permeability, flux density and magnetizing force of wound core.

H = magnetizing force(oersteds)

N = number of turns

l = peak magnetizing current(amperes)

= mean magnetic path length(cm)

Bmax = maximum flux density (gausses)

Erms = voltage across coil(volts)

f = frequency (hertz)

Permeability - Flux Density - Magnetizing Force

Inductor specification

a) Formula to calculate L at 0Ampere

LN = AL N2 10-3

The Nominal inductance table on page 8 shows the AL value of CM270125 to be 157.

Therefore, L ( 0A) = 157 222 0.001 = 76 (μH)

b) Determine DC magnetizing force (H) by using Ampere’s law to achieve the roll off.

H = 0.4 Nl /

H = 0.4 3.14 22 10 / 6.35 = 43.5(Oe)

The magnetizing force(dc bias) is 43.5 oersteds, yielding 59% of initial permeability on page 12.

The inductance at 10Ampere will decrease the inductance by 59% compared with 0Ampere.

Therefore, L( 10A) = 76 0.59

Therefore, L( 10A) = 44.8 (μH)

Inductance calculation by AL vs Nl Curve is also available on 24page.

For toroidal powder cores, the effective area(A) is the same as the cross sectional

area. By definition and Ampere’s Law, the effective magnetic path length is the ratio

of ampere-turns(NI) to the average magnetizing force. Using Ampere’s law and

averaging the magnetizing force gives the formula for effective path length.

Powder cores have low hysteresis loss, minimizing signal distortion, and low residual loss. The total core loss at low flux densities is the

sum of three frequency dependent losses of hysteresis loss, residual loss, and eddy current loss. The core loss is calculated from the

following Legg’s equation.

When a varying magnetic field passes through the core, eddy currents are induced in it. Joule heat loss by this currents is called eddy

current loss. Hysteresis loss is due to the irreversible behavior in hysteresis curve and equal to the enclosed area of the loop.

The other core loss is called residual loss.

Where Rac = core loss resistance (ohms)

OD = outside diameter of core (cm)

ID = inside diameter of core (cm)

A = core cross section (effective area)

= mean magnetic path length (cm)

The Q factor is defined as the ratio of reactance to the effective resistance for an inductor and thus indicates its quality. The Q of wound core can

be calculated using the following formula, when neglecting the effects of self-resonance caused by the distributed capacitance resulting from the

differential voltage between adjacent turns.

Solution

a) Calculate NI (Ampere Turns) NI = 22Turns X 10Ampere = 220

b) Read the AL value of CM270125 using the AL vs NI curve on page 43.

AL value of CM270125 yields 92.6 when NI is 220.

c) Calculate L at 10Ampere by using formula; LN = AL x N2X 10-3(μH)

Therefore,

L( 10A) = 92.6 222 0.001

= 44.8(μH)

Inductance calculation by Permeability vs DC Bias Curve is also available on 43Page

- Core : CM270125

- Number of Winding : 22Turns

- Current : DC 10Amperes
