With the rapid development of modern technology, more types of power adapters and switching power supplies continue to appear, but no matter the size and shape of power adapters or switching power supplies differ, their internal structure and characteristics generally do not change much.The followin... read more
Switching power supply is a power supply is widely used in recent years, it has small volume, light weight, low energy consumption and convenient use, widely used in all kinds of electronic products. But as a result of switching power supply control circuit is more complex, the output ripple voltage... read more
The toroidal transformer double-line is to make the midpoint voltage of the output or input just half of the output voltage at both ends of the head and tail. The double line is generally not used for the primary winding because the voltage difference between the two lines is too high and easy to br... read more
In the past 35 years, our team has investigated thousands of transformer failures. There are many reasons why a transformer may fail, but there are some common reasons. We have identified 10 common causes that can help you determine whether a failure should occur. Below we focus on the causes of tra... read more
The quality of the toroidal transformer is mainly determined by four factors: iron core, enameled wire, insulating material and winding process. Why do you say that? 1. The good quality iron core silicon steel sheet is thin, not only has high magnetic permeability, low loss, but also the iron core i... read more
