Toroidal Transformers produce less radiated noise (50 or 60 Hz hum) and generally are smaller and lighter than conventional laminated steel core transformers.
Conventional transformers have rectangular cores, whereas toroidal transformers have circular ('toroid' means 'circular') cores. The windings are placed around conventional cores by removing the top 'yoke' (horizontal member) of the core, making them easy to manufacture. For a toroidal transformer, however, the windings have to be actually wound around the core, making them much more difficult and, therefore, expensive to manufacture. Toroidal cores have less magnetic leakage than conventional cores, but are limited to small applications (e.g. hi-fi amplifiers, etc.), whereas conventional cores can be manufactured to any size.
Most computer power supplies contain both. The transformers are usually toroidal transformers for high efficiency and compactness.
Yes, you can use a low voltage transformer for LED strip lighting, provided the transformer is compatible with the voltage required by the LED strips, typically 12V or 24V. Make sure the transformer can handle the total wattage of the LED strips you plan to use. Additionally, it's essential that the transformer is designed for LED applications to ensure optimal performance and efficiency.
For higher current applications you would need a power transformer, for lower current applications you would need an adapter transformer.
To convert 12VAC to 24VAC, you can use a step-up transformer designed for this purpose. Connect the 12VAC input to the primary side of the transformer, ensuring the connections are secure. The transformer will output 24VAC on the secondary side, which can then be used for your applications. Always ensure that the transformer is rated for the appropriate load and voltage specifications.

Transformers are just as efficient in step up or step down applications. Transformers for transforming 480 to 240 single and three phase can be reverse connected. The label may have it listed as a step down 480 to 240, but you can connect 240 supply to the secondary side and get 480 out of it. I have had several applications where I have done this and the transformers performed with no problems. Another good source of information for transformer applications and connections is the manufacturers themselves.

yes we can place auto transformer in place of original transformer
Other terms for a transformer include "voltage transformer," "power transformer," and "distribution transformer." In specific contexts, it may also be referred to as a "step-up transformer" or "step-down transformer" depending on its function in increasing or decreasing voltage levels. Additionally, in electrical engineering, it may simply be called a "reactor" in some applications.
Ideal transformer is useful in understanding the practical transformer..i does't have losses...
why should we use pulse transformer rather than ordinary transformer
