Hysteresis Loop Tracer for Transformer Core Materials

Approx. component budget: Rs. 3,000 - 6,000

Objective

Compare the loss and saturation of different core materials such as silicon steel and ferrite.

What you will build

A circuit with a primary and secondary winding on a core sample that displays the B-H loop on an oscilloscope or microcontroller screen and computes the core loss.

Results you can expect

• B-H loops for 3 cores
• Hysteresis loss per cycle
• Saturation flux density
• And the effect of frequency on the loop area

What you will learn

Magnetic materials, hysteresis loss and integrator circuits, useful for transformer and inductor design.

Tools and notes

Core samples, RC integrator, function generator, oscilloscope or ADC, Python plotting. Use low voltage and current only.

Resume points from this project

• Built and tested Hysteresis Loop Tracer for Transformer Core Materials; objective: compare the loss and saturation of different core materials such as silicon steel and ferrite.
• Measured and analysed b-H loops for 3 cores and hysteresis loss per cycle; wrote the report and presented the results in a viva. Add your own numbers: [x].

Replace [x] with your own measured results. Write only what you really did.
