In today's complex electromagnetic environment with highly dense electronic equipment, the performance of Common mode inductor is crucial. So, how to evaluate the actual effect of Common mode inductor in such environment?
First, it can be preliminarily evaluated by testing its insertion loss. Insertion loss reflects the ability of Common mode inductor to suppress common mode interference signals. In a complex electromagnetic environment, use professional test instruments to measure the change in signal strength within a specific frequency range in the circuit before and after the Common mode inductor is connected. The greater the insertion loss, the stronger the attenuation effect of Common mode inductor on interference signals, and the better the actual effect.
Secondly, observe the degree of improvement of electromagnetic compatibility (EMC) by Common mode inductor. In actual electronic systems, complex electromagnetic environments may cause mutual interference between devices and affect the normal operation of the system. By performing EMC tests on the equipment before and after the installation of Common mode inductor, check whether the indicators such as radiated emission and conducted emission are effectively reduced. If Common mode inductor can significantly reduce the electromagnetic interference level of the equipment and improve the electromagnetic compatibility of the system, then its actual effect in a complex electromagnetic environment is relatively ideal.
Secondly, consider the stability and reliability of the Common mode inductor. In a complex electromagnetic environment, factors such as temperature and humidity may change greatly, and there may also be various sudden electromagnetic interference pulses. Common mode inductors should be able to maintain stable performance under these harsh conditions without overheating, burning or performance degradation. The stability and reliability of Common mode inductors can be evaluated through long-term operation tests and simulated harsh environment tests.
In addition, the actual effect of Common mode inductors can also be evaluated from a cost-effectiveness perspective. Although high-performance Common mode inductors may perform well in suppressing interference, if the cost is too high, it may affect its feasibility in practical applications. Therefore, it is necessary to comprehensively consider the performance and price of Common mode inductors and select cost-effective products.
In short, evaluating the actual effect of Common mode inductors in complex electromagnetic environments requires comprehensive consideration of multiple aspects such as insertion loss, electromagnetic compatibility improvement, stability and reliability, and cost-effectiveness to ensure that they can provide effective electromagnetic interference suppression for electronic systems and ensure the normal operation of the system.
