Problems solved by technology
[0002] Commonly used impedance analyzers can only measure the impedance under static conditions or the impedance under low current superposition, and cannot test the impedance characteristics of magnetic cores under dynamic conditions.
In the actual working process, the magnetic core may be susceptible to changes in impedance due to external influences. If a magnetic core whose impedance characteristics do not meet the requirements is used for work and application, it may affect the quality of its application device.
