Absorption magnetic ring, also known as ferrite magnetic ring, referred to as magnetic ring. It is a commonly used anti-interference component in electronic circuits, which has a good suppression effect on high-frequency noise.

During the test, we often encountered such a situation: although the design engineer connected a power filter to the power line of the equipment, the equipment still could not pass the "conducted disturbance voltage emission" test, and the engineer suspected that the filtering effect of the filter was not good. Constantly replace the filter, still can not get the desired effect.

Most of the magnetic rings need to be painted to facilitate the distinction. Generally, the iron powder core is distinguished by two colors.

According to the application of the inverter filter, it can be divided into the following types:

Any device capable of processing a signal can be called a filter. In modern communication equipment and various control systems, filters are widely used.

What are the differences between inverter filters and reactors? Let's take a look at it in detail.

As the name implies, the inverter filter is a special filter specially developed for the characteristics and laws of the harmonics generated by the inverter. It is an LC filter. Inverter Input Filter Overview Inverter filters are mainly passive components consisting of inductors, capacitors and resistors.
