1. Some friends will ask how the voltage regulator is regulated? The structure of the voltage regulator is the same as that of the audio transformer, but the iron core is made into a toroidal coil and wound around the toroidal iron core. The secondary coil tap uses a slidable brush contact to make t... read more
Static electromagnetic devices that convert electrical energy and transfer electrical energy from one circuit to another are called toroid transformers. EI transformer is one of the electronic transformers, which is defined according to the shape of the iron core. Because the iron core of EI transfo... read more
Knock on the key point - the working principle of small transformers! The working principle of the small power transformer has been touched in our high school textbooks. It is one of the crystallizations of human wisdom, which represents that human beings use electric current to transform all aspect... read more
The power supply circuit is an important part of the motherboard. According to its working principle, the power supply circuit can be divided into linear power supply mode and switching power supply mode. So what is the difference between these two power supply methods? The following is a detailed i... read more
1. The reason why the switching power supply always has no voltage output The switching power adaper supply always has no voltage output, which means that after pressing the power switch to turn on, the output terminal of the switching power supply is always 0V. This is because switching power suppl... read more
