No, you're hysteresis losses are set by Bmax, frequency, and material. The function is highly nonlinear and the loss goes up disproportionately with Bmax.
When designing power Transformers, you typically want the hysteresis + eddy losses to equal the copper losses.
Changes in the magnetic field will always produce hysteresis loss. Since transformer works based on the electromagnetic induction. Hysteresis loss is predominant.
It can be minimized by stampings with suitable design.
Hysteresis losses are a function of the magnetic characteristics of the magnetic circuit, so there is very little you can do to minimise hysteresis losses other than to reduce the primary voltage to a transformer if that is at all practicable. These losses are really in the hands of the manufacturers who design and manufacture magnetic circuits.
The power lost by hysteresis depends on the peak flux density in the core. If the transformer is getting hot even when on no load, it should be run at a lower voltage.
Core loss is one of the many fixed losses in a transformer. This means that no matter the loading of the transformer there this loss would be fixed unlike copper loss which depends on the loading of the transformer.
hysteresis loss = N1/N2 R2/R1 C1/A1 (area of the loop)(vertical sensitivity) (horizontal sensitiivity
To minimize hysteresis loss
Just like a transformer, the core losses are a combination of eddy current losses and hysteresis losses.
Hysteresis losses are a function of the magnetic characteristics of the magnetic circuit, so there is very little you can do to minimise hysteresis losses other than to reduce the primary voltage to a transformer if that is at all practicable. These losses are really in the hands of the manufacturers who design and manufacture magnetic circuits.
The efficiency of a simple transformer is limited by resistive loss in the wiring, and by hysteresis (magnet related) losses in the transformer core. You may limit the resistance loss by using superconductors at very low temperatures. But not practical for most situations. (Yet!)
what is hysteresis losses
The power lost by hysteresis depends on the peak flux density in the core. If the transformer is getting hot even when on no load, it should be run at a lower voltage.
In a transformer, there are two basic types of losses that are broken down even further: iron loss and copper loss. Hysteresis loss is part of what makes up the iron loss, but is not the only part of iron losses.
Core loss is one of the many fixed losses in a transformer. This means that no matter the loading of the transformer there this loss would be fixed unlike copper loss which depends on the loading of the transformer.
No
hysteresis loss = N1/N2 R2/R1 C1/A1 (area of the loop)(vertical sensitivity) (horizontal sensitiivity
there are several losses in a transformer that prevent it from attaining 100% efficiency. One is core loss, which can be divided into Hysteresis losses, Eddy currents and Magnetostriction loses. see for more details http://en.wikipedia.org/wiki/Transformer#Energy_losses
Overexcited Transformer.Operation above the rated supply voltage causes the ferromagnetic core to enter saturation; this means that the primary inductance is reduced and since the primary current is limited by primary resistance +inductance then the primary current will increase and possibly cause the primary winding current capacity to be exceeded. Also the iron core hysteresis loss will likely increase and cause the core temperature to rise. We have not considered eddy currents in the core, probably these are less than the hysteresis core loss.Addition:also the stresses that caused by increasing the voltage will over heat the transformer by mean the life time is redused, for example: if the life time for a transformer is 20 years this number will decrease due to operating the transformer on a higher voltages than the rated...
Iron losses (Pi) are independent of of load which occur due to pulsation of flux in the core. Iron losses include both Hysteresis loss and eddy current loss and is same at all the loads.
