Basic knowledge of filters

Jun , 21 2023

The Line filter is a filter circuit composed of capacitance, inductance and resistance. A filter can effectively filter out a specific frequency point in the power line or frequencies outside of that frequency point, obtaining a specific frequency power signal or eliminating a specific frequency power signal. A filter, as the name suggests, is a device that filters waves. Wave "is a very broad phy...

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...

Series and parallel connection of capacitors

Feb , 23 2024

Capacitor series connection: The total capacity decreases, but the withstand voltage value increases. The withstand voltage value is the sum of the withstand voltage values of two capacitors. Capacitor parallel connection: The total capacity increases, and the voltage withstand value is taken as the voltage withstand value of the smallest capacitor. If two capacitors are exactly the same, the volt...

A brief introduction to EMI

Jun , 14 2024

What is an active power filter Active Power Filter (APF) is a new type of power electronic device used to dynamically suppress harmonics and compensate reactive power, which can compensate for harmonics and reactive power changes in magnitude and frequency. The reason why the active filter is called active, as the name suggests, the device needs to provide a power supply (to compensate for the har...
