It is surprising to find out just how many different common applications there are for switched mode power supplies, or more simply known as SMPS in the electronics field. These power supplies not simple components, but one simple option in the design are the SMPS transformers, which are essential in the use of the power supplies.
There are actually several different types of designs of SMPS, and each one has a need for different SMPS transformers. In general, the input will be an AC mains supply. By passing through the SMPS transformers, it creates a DC to DC converter that is at a regulated level without fluctuations and variations.
Additionally through the design of the SMPS it also possible to have the component operate as an AC to DC converter or to step up or step down the power, which is ideal for systems operating under battery power.
The Importance of the Transformer
The SMPS transformers are important in the SMPS in preventing the EMI or electromagnetic interference from the AC mains supply to the other side of the system or for other electronic components in close proximity.
Some devices use a transformer at the AC input or in the line while others use the transformer within the control part of the actual power supply. In this situation, the transformer is essential in providing electrical isolation as well as allowing for specific output voltage.
The output voltage in SMPS transformers is determined by the number of windings. Different designs and applications of these components will include fewer or a greater number of windings to create the required voltage.
Size and Other Features
One of the most important features of SMPS transformers is their physical size. They are small compared to other types of transformers, and they are also more operationally effective, which makes them an ideal choice in most types of applications.
The core area, the frequency, and the magnetic flux produced will all impact the terminal voltage. Most of the top SMPS transformers are made using a ferrite material combined with high frequencies, which words to effectively keep the size down without compromising on stability and performance.
There is a wide range of different applications for SMPS units. They can be found in all types of chargers, including those for phones and computerized devices, in vehicles, and in the telecommunication industry. In each of these types of applications, SMPS transformers will also be in use, allowing the SMPS to function effectively.
