The function and principle of power filter shell are briefly described

Filter shell manufacturers brief you on filter function

A filter is a network of inductors and capacitors that separates the mixed AC/DC current. In the power rectifier, the more pure DC output is obtained by filtering the ripple in the pulsating DC with this network. The basic filter is composed of a capacitor and an inductor, called L-type filtering. All types of filters are set to form L-type single-section filters. A filter is a device used to eliminate interference noise by filtering the input or output to obtain a pure direct current. A circuit that effectively filters out a frequency point at a particular frequency or a frequency other than that frequency point is a filter whose function is to obtain a specific frequency or eliminate a specific frequency.

What is the role of the Power filter housing?

PowerFilter housingis a passive bidirectional network, which is an electrical equipment that effectively filters out the frequency point of a specific frequency in the power supply or the frequency other than that frequency point. When we choose the power filter, we should mainly consider the three aspects of the indicator first is the voltage, current, followed by the insertion loss, is the structure size. Because the inside of the filter is generally encapsulated, environmental characteristics are not the main problem. However, the temperature characteristics of all the sealing materials and filter capacitors have a certain influence on the environmental characteristics of the power supply filter.

Filter shell manufacturers explain the principle of power filter for you

A power filter is a passive two-way network, one end of which is the power supply and the other end is the load. The principle of the power filter is a kind of-impedance adapter network: The greater the impedance adaptation of the input and output side of the power filter and the power supply and load side, the more effective the attenuation of the electromagnetic interference.

A power filter is a filter circuit consisting of capacitors, inductors, and resistors, also known as a "power EMI filter", or an "EMI Power filter", a passive two-way network, one end of which is a power supply and the other end is a load. The principle of the power filter is a kind of-impedance adapter network: The greater the impedance adaptation of the input and output side of the power filter and the power supply and load side, the more effective the attenuation of the electromagnetic interference. The filter can effectively filter out the frequency point at a specific frequency in the power cord or the frequency other than that frequency point, obtain a power supply signal of a specific frequency, or eliminate the power supply signal after a specific frequency.
