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 introduction by Caixing Electronics, a Guangdong linear power supply manufacturer.1. Linear power sup read more
1. The reason why the switching power supply always has no voltage outputThe 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 supplies do not oscillate. Further confirmation is to measure the voltage of the switching power supply af read more
There are different frequencies in the transformer, and the applicable environment is also different; if it is a high-frequency transformer, it is specially used for the high-frequency stage, and the low-frequency transformer is a special transformer in the low-frequency range. Regardless of the operating frequency, the audio transformer transmits by electromagnetic induction. If the transmitted e read more
It is well known that the function of the power isolation transformer is to help transmit power, voltage conversion and isolation, so it has been widely used in power supply technology and power electronics technology.The most basic type of power transformer consists of two sets of coils with wires wound together inductively coupled with each other. When an alternating current (with a known freque read more
Toroidal transformers have the characteristics of low noise, less heat, small size and high conversion efficiency. They have been widely used in instruments, medical and health, industrial automation equipment, household appliances and other industries in today's society. It exhibits excellent performance, far exceeding the performance of U-type and E-type transformers.According to my prelimin read more
