Toroidal transformers have several advantages over conventional transformers. The design and calculation used to make these transformers is different for different manufacturers, which makes the products different from each other. Toroidal transformers are widely used in audio amplifiers. When purchasing your toroidal transformer, it is important to know exactly the desired specification and the possible uses it will have. In the video, we use transformers manufactured by Toroid do Brasil. For more details, sales price, applications, operating frequency and other information, visit the website of this manufacturer at the link below: http://www.toroid.com.br/ Calculating a transformer to wind yourself, making a homemade transformer is an option for some enthusiasts or designers in prototypes. Especially for small and higher frequency transformers, the calculation can be simpler and the formulas are easily found on the internet. There are also toroidal transformers used as insulators. The definition of inductors and toroidal transformers is well explained in the video. Among the objectives of this video, we highlight: Presenting the characteristics of toroidal transformers. We cover the following topics in this video: Toroidal transformers have the same operating principle as conventional transformers, but due to their ring-shaped construction features, their efficiency is higher. One of their main features is that they do not have a GAP, that is, there are no openings or cuts in their core, which is not always possible in other types of transformers. Because they do not have a GAP, their construction geometry makes them superior and reduces losses. Main advantages: Low radiation of the magnetic field around the transformer, allowing less interference in sensitive electronic circuits. Low losses, providing lower consumption due to the small current consumed at no load. Voltage variation at the power output is lower, that is, the difference between the output voltage with and without load (at no load) is lower than that of a conventional transformer. Smaller size, between 40 and 60% smaller and lighter than conventional transformers. Easy assembly in equipment, and can be fixed with just 1 screw or even with pins (for PCB) or plastic clamps, reducing assembly time. Silent operation, that is, the mechanical noise from the vibration of the core practically does not exist. Parts highlighted in this video: 00:44 - There is a defined relationship between the turns of a transformer that define its transformation ratio. 01:03 - The base of every transformer comes from electromagnets. 01:45 - Among the types of transformers there are autotransformers and these are widely used in everyday life. 02:14 - It is important to know that every transformer, even without a load, has a certain consumption, called no-load consumption. 03:16 - The main quantity transformed in transformers is electrical voltage. 03:40 - Transformers are inductive loads and therefore modify power as we know it. 04:19 - The concept of electrical current is important in the study of transformers.
