Magnetic ring selected, and how to detect the magnetic ring toroidal inductor is good?
1. Use calipers to check whether the size of magnetic ring inductance meets the required standards

The color of the magnetic core after sintering is not necessarily related to the paint color after spraying. It's just some conventional correspondence. Like green - high dot; Two colors - iron powder core; Black + print - iron, silicon, aluminum, etc.
The color of the magnetic ring is habitual. If the customer has no special requirements, the factory will
match the color according to the manufacturer's standards and requirements. High permeability products, the higher the permeability, the temperature is likely to be lower, but the inductance is higher, the number of winding can be less, line diameter can also choose a larger.
In order to solve the problem of the magnetic ring waveform, this paper gives an example of how to identify the magnetic ring waveform.
The yellow is the primary current waveform, and the other two are the secondary voltage waveform
The smooth section in the secondary current waveform is the dead zone time of alternating conduction of two pipes. In practice, the current of two secondary loops is defined as the same current direction, and the waveform should be the opposite of each other.
