Vacuum potting fix the lamination steel and bobbin, and at the same time, ensure that the transformer will not corrode when placed in the air for a long time. It is perfect for applications in harsh environments, where dust, lint, moisture and corrosive contaminants can accumulate.
Since traditional transformers can’t meet today’s efficiency requirements, high-frequency transformers were invented. High-frequency transformers improve efficiency, as well as save power, and have a longer service life than standard transformers.
The basic principles of step-up transformer and step-down transformer are the same.The main difference between a step-up transformer and a step-down transformer is their performance during their operation. The step-up transformer is designed to increase the output value, while the step-down transformer is designed to decrease it. Here, we discuss the differences between step-up transformers and step-down transformers, including definition, voltage，windings, conductor sizes, magnetic fields, and applications.
Learn Unicreed which types transformers could be used in PCB board, such as the following:
1. 50/60Hz Encapsulated Transformer (0.35VA-24V)
2. Toroidal Transformer (15VA-3000VA)
3. Open frame/Linear Transformer (1.1VA-600VA)
4. High Frequency Transformer
5. Common Mode Choke(1.5W-35W)
6. Coils
Lamination material for transformers is silicon steel, silicon steel is a kind of steel containing silicon (silicon is also called silicon), and its silicon content is between 0.8% and 4.8%. Silicon steel has the characteristics of high magnetic flux, low iron loss, low temperature rise, low no-load current, low noise, etc. The silicon steel can generate a large magnetic induction intensity in the energized coil.
A transformer works in the flyback circuit, the output and input of the secondary transformer are reversed. The transformer’s magnetic core stores energy during operation, so the magnetic density is higher than other methods， the flyback transformer has a much lower power rating.
17 core types used for high frequency transformer
There are many types of high-frequency transformer cores. Below are 17 core types that are most commonly used in high-frequency transformers,I hope that this information will be helpful.
You must first determine the size of the power transformer to be designed, and then calculate the core AE area by using a formula or experience, and finally determine the type of core.
It is important to know the position of the transformer in the pcb, otherwise the designed transformer is too large for the PCB, and the power is too low to meet the requirements.
Here are some high frequency transformer applications:
1.Voltage test equipment
2.Mobile phone charger
3.Switching power supply
4.Lighting equipment
5.X-ray equipment
6.Communication system
7.Industrial robots
8.Photography technology equipment
9.Medical equipment
10.Laboratory equipment
