In electronics today, the torodial transformer is being used a great deal. In fact, this component has several advantages over other transformers (which contain many small wires wrapped around a core). Here are some of the main reasons they are being used today.
What is a Torodial Transformer?
In electricity, transformers are an important part of many circuits. For example, they can be used to lower common household current to just a few volts, making it possible to use normal AC power as the source for low voltage circuitry like laptop computers and video game consoles. In addition, a transformer can increase voltage a great deal and a good example is the ballast in a fluorescent light fixture or microwave oven transformers.
The term “Toroid” refers to a specific configuration. A typical torodial transformer utilizes a hollow core or form in the shape of a donut. This form often contains iron in powdered form. Wire is coiled around the form to create the transformer. This also forms an inductor.
What is an Inductor?
An inductor is created by wrapping wires around a magnetic core and passing current through the wires. When this happens, a magnetic field or flux is created and this offers resistance to the current flow. It also creates voltage and this is known as inductance. During the process of induction, the resistance created helps maintain a constant flow of current. This is essential for many electronic systems like LED lighting. A torodial transformer is used to transform or change the amount of voltage while maintaining a constant supply.
Benefits of Torodial Transformers
One of the most important benefits of torodial transformer is less magnetic fields created. This also makes for less RF or EMI interference within circuitry. Plus, in a world of miniaturization where everything seems to be getting tinier, the torodial transformer fits right in with its much smaller size and weight. It is being used today in a wide range of applications.
The torodial transformer is very efficient in design and operation. Because the way the windings are wrapped around the core, the flux density is far greater than any standard wrapped transformer. For example, the core is commonly made of iron filings or powder and this creates molecules all flowing in the same direction as the magnetic flux. When you have a smaller, lighter, and more efficient transformer this is the answer to many modern electronic problems.
