A power supply filter, also known as a “power EMI filter†or an “EMI power filterâ€, is a passive two-way network that is effective for frequencies at specific frequencies in the power supply or frequencies outside the frequency. Filtered electrical equipment, one end of which is connected to the power supply, and the other end is connected to the load.
Power filter working principle
A power supply filter is a passive two-way network that has a power supply at one end and a load at the other end. The principle of the power filter is one - impedance matching network: the greater the impedance adaptation between the input and output sides of the power supply filter and the power supply and load side, the more effective the attenuation of electromagnetic interference is.
