There are all kinds of EMI noise in 220V/50Hz AC power grid or 115V/400Hz AC generator, among which artificial EMI interference source
Modular power supply noise filters are widely used, mainly to filter out noise and interference in the power supply. The basic principle is to use the impedance characteristics of capacitors, inductors and other components to filter out noise at a specific frequency. The filter can allow the useful signal to pass smoothly, while preventing noise interference of specific frequencies from entering the circuit. By selecting appropriate component values and filter structures, noise of different frequencies can be effectively suppressed. In practical applications, the filter is usually closely integrated with the power module to ensure the stability and reliability of the power supply. Therefore, understanding the principles and applications of filters is essential to improve the performance of electronic devices.
