What is AL in a transformer? Why does multiplying AL by the square of the number of turns result in the inductance value? Do you understand? If you are involved with transformers, you have likely heard the term "AL" at least once. However, those not involved with transformers may have never heard of this term at all. Even among those involved with transformers, there may be many who only understand that "multiplying AL by the square of the number of turns gives the inductance value." For such individuals, this foundational course is a must-see. We explain why multiplying AL by the square of the number of turns results in the inductance value, and what AL is, using formulas for concrete understanding. Please take a look.

I would like to reintroduce the common implementation possible list with other companies that I proposed earlier. To all the design and purchasing personnel considering replacements, and to all trading companies, this list allows you to check the part numbers that can be implemented as replacements between other companies' products and ours. Please use it as information when considering alternative proposals! Common Implementation Possible List https://premium.ipros.jp/tokyocoil/catalog/detail/507161/?hub=158

What is the role of a transformer? Depending on how it is used, it has various roles. Among them, the easiest to understand is voltage conversion. It converts voltage based on the ratio of the number of turns on the primary side to the number of turns on the secondary side. It is understood that voltage is converted according to the turns ratio. However, to be more specific, a transformer takes electrical energy input on the primary side, converts it into magnetic energy within the transformer, and outputs electrical energy on the secondary side. The conversion of voltage according to the turns ratio refers to the details of "electrical energy on the primary side" and "electrical energy on the secondary side." There is no explanation regarding the detail of "conversion into magnetic energy within the transformer." In fact, this is a difficult part. This time, I will explain "magnetic energy."

Electrical resistance is defined as: R (electrical resistance) = V (voltage) / A (current) or R (electrical resistance) = L (length) / (σ (conductivity) × S (cross-sectional area)) I believe many people understand and remember these formulas. Now, when asked about magnetic resistance, those who find it hard to recall might be more common compared to electrical resistance, right? There’s no need to memorize it, but understanding it can be helpful in transformer design, so please take a moment to check it out.
