Exploring the importance of UPS power supply in the composition of computer rooms

Jul , 20 2023

For data centers, faults are inevitable during the operation of the power system. Although the probability of a malfunction occurring is small and the duration is not long, the consequences are often very serious. When a power system malfunctions, the operating state will undergo a sharp change. So the application of a UPS power supply is particularly important for the uninterrupted operation of t...

Selection of the Function of Power Filter Capacitors

Aug , 10 2023

1 、The Role of Power Filter Capacitors The power filter capacitor is a type of capacitor connected in series between the power output and the load, mainly used to filter high-frequency noise in the power supply and ensure the stability and reliability of the power output. At the output end of the power supply, due to the conversion of AC power to DC power, there will be a certain AC component in t...

The working principle of anti reverse diode

Aug , 10 2023

Anti reverse diode, also known as reverse protection diode, is a component used in a circuit to prevent reverse current from flowing in. This type of diode is usually composed of a PN junction diode. Under normal operating conditions, the pressure difference between its P and N poles will cause the diode to conduct, while under reverse conditions, this pressure difference disappears and the diode ...

The Role of AC Capacitors in High Speed Circuits

Aug , 18 2023

1、Introduction For low-frequency circuits, resistors and capacitors can be analyzed as ideal devices. However, in high-frequency circuits, these two devices will not be "ideal". Today, our main discussion is about the issue of AC capacitors, which are commonly known as AC coupling capacitors. Their main function is to filter out the DC component of the signal, which is symmetrical about the X-axis...
