10. More economical:

It can work, in fact, the transformer is usable in circuits ranging from 45Hz to 60Hz. The transformer 50/60Hz is widely accepted to be universal in use. The materials are the same, but there is a variation in the number of turns. Transformer coils operating at a power supply frequency of 50Hz require a little more per volt than those that operate at a power supply frequency of 60Hz. Thus, we find that the cores of both transformers are exactly the same…

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

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
