Dataset

[Sairamiitdh]

Hi Prof. Minjie Chen,

How can we access the dataset?

Can you please let us know if the dataset given in a file will correspond to one continuous sequence of voltage pulses from a converter?

Best wishes,
Sai Ram.

The dataset is just released on the main Github page under news with a dropbox link.

Yes this will correspond to one continous sequence of voltage excitations.

Hi Prof. Minjie Chen,

Thank you very much for your response. We can download the data. I need clarification on understanding the files in each folder. For example, under the N87 folder, the file N87_7_B contains all the flux density values, and the corresponding field intensity values are in N87_7_H. I can understand that each row of these Excel files corresponds to the individual sequence of data, and the time step is given in N87_7_T. Please correct me if I am wrong.

Best wishes,
Sai Ram.

In the file N87_7_T, the values would be the temperature information, which would match each row in the corresponding N87_7_H and N87_7_B .

Timestep information is from sample rate of 16Mhz or (MegaSamples/second) giving a constant time step between current and next point of 1/(16 Mhz) or 62.5 nanoseconds(in the same row in H and B).

Can data points in separate rows can be assumed to have no time relationship? Or independent in time?

[minjiechen]

Yes, confirm correct.

Yes, data points in separate rows are independent, they are collected in different magnetization and demagnetization sequences.

Hi Prof. Minjie Chen,

Is it possible to know the dimensions and number of the turns of coils of the magnetic circuit used for these measurements?

[minjiechen]

Yes, we can do that. We will add this info to the Dropbox folder.

[Sairamiitdh]

Thank you.

[minjiechen]

The additional measurement data was added to each material zip folder as a Test_Info file.

Hi Prof. Minjie Chen and Team,

Thank you for the tutorials, and they are very useful.

I have one question related to the dataset. I understood that in each set of Excel files, we have multiple rows of data that correspond to a sequence of excitation. Is there any correlation between the rows in a given file? Also, is there any correlation between the data given in different Excel files? That means what I would like to understand is whether the duty ratios and amplitude of the voltage waveforms in these files for a given material follow any increasing or decreasing order.

[minjiechen]

No all rows are independently collected experimentally, and are independent from each other.
