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
Unicreed is a professional PCB transformers manufacturer in China, we mainly focus on developing and producting 4 kinds of PCB transformer: Encapsulated Transformer, Open Frame/Linear Transformer, Toroidal Transformer and High Frequency Transformer. The following are our inspection contents and requirements for our 4 kinds of PCB transformers.
Transformer is an important electronic component. Nowadays, small transformers are widely used on PCB, which brings great convenience to people’s production. However, it is difficult for people with no previous transformer experience to purchase the right transformer smoothly and practically. Now, let’s talk about how to choose small transformer for PCB
11 Advantages of High Frequency Transformers
1. Small size: A ferrite material high-frequency transformer has the advantages of high conversion efficiency and small size.
2.Low cost: Since the amount of silicon steel sheet and copper wire used in the transformer is related to the rated induced potential and current of the winding, the winding capacity is lower, and materials are also used less and the cost is lower.
3.More efficient：Due to the reduced copper and silicon steel wires and sheets, at the same magnetic flux density and current density, the copper and iron losses are reduced compared with the double-winding transformer, so the efficiency is higher.
