00:00In this video, we'll delve into the fascinating world of toroidal transformers.

00:04But first, let's solidify some foundational concepts.

00:08Current induces a magnetic field which reciprocally can induce current,

00:12enabling wireless power transmission,

00:15particularly effective with spiral or coil shapes.

00:18Transformers, as the name suggests, transform voltage and current

00:23while maintaining a relatively constant power output,

00:26relying on the difference in turns between primary and secondary coils.

00:31Cores with high magnetic permeability amplify magnetic flux,

00:36crucial for energy transfer between coils.

00:39Now, on to toroidal transformers.

00:43Their toroidal shape optimizes magnetic field distribution,

00:47enhancing efficiency and compactness.

00:50With the coil completely enveloping the core, eddy currents are minimized,

00:54leading to lower operating temperatures.

00:57This design inherently facilitates better induction throughout the coil.

01:02But let's not overlook the secondary winding.

01:05Constructing a toroidal transformer involves a toroidal core,

01:09typically coated to prevent direct contact with the primary winding.

01:14Layers are added to insulate the primary winding from the secondary,

01:19followed by washers and fasteners to secure the assembly.

01:22The primary winding usually has more turns than the secondary,

01:26resulting in voltage reduction.

01:29This ratio determines the output voltage,

01:32exemplified by a simple mathematical calculation.

01:36Adding secondary coils allows for multiple output voltage options,

01:41offering flexibility in various applications.

01:44Furthermore, this flexibility extends to the primary winding,

01:48where different combinations cater to varying input voltages,

01:52allowing for a wide range of output possibilities.

01:56However, despite their versatility, toroidal transformers aren't omnipresent.

02:03Their complex construction and higher cost, coupled with size limitations,

02:08restrict their widespread use, typically to lower kilovolt ampere ratings.

02:13So while toroidal transformers offer efficiency and compactness,

02:17their intricate design and higher production costs

02:20limit their application in certain scenarios,

02:23emphasizing the importance of considering various factors

02:26when selecting transformers for specific purposes,

02:29like comment, share, and follow.
