Be aware of these tips when using inductors
Feb 27 , 2021
The main uses of RF inductors are diverse, and can be used in various structural features to consider performance testing schemes for special applications. Matching, resonators and choke coils are the main common uses of inductors in RF power circuits. Matching includes removing the characteristic impedance mismatch and minimizing the reflective surface and loss of the middle route of power circui...

Inductor selection analysis, let's understand together
Feb 27 , 2021
You should be clear about the scope of inductance in the power circuit. Since the inductance is mostly not stable during the entire working period of the components, it is particularly important to grasp the scope of the effective value. For inductors used in power switching applications, the overall goal of allowable harmonic distortion current and transient response will determine the inductance...

Transformer internal structure transformation ratio conversion method
Aug 12 , 2021
The current transformer is an instrument and equipment that converts a large current on the primary side into a small current on the secondary side for accurate measurement based on the basic principle of the magnetic effect of the current. It is mainly composed of a closed iron core and windings. Transformer The number of turns of the primary winding coil is very small, which is stringed in the r...

The higher the Q value, the lower the loss when winding the coil
Aug 12 , 2021
Let’s first talk about the definition of inductor quality factor Q Coil The Q value is the basic main parameter to consider the inductance. It refers to the ratio of the inductance exhibited by the inductance to its equivalent circuit loss resistance when the inductance works under a certain frequency of AC voltage. The higher the Q value of the inductor, the smaller its loss and the higher the ef...

Analysis of Rogowski coils Start to understand step by step from three aspects
Mar 13 , 2022
What is a Rogowski coil? The Rogowski coil is a flexible clip-on hybrid inductor coil that can be easily coiled around a current conductor for measurement, capable of measuring large currents of several thousand amperes without expanding the size of the voltage transformer. Rogowski coils are electronic voltage transformers used to measure alternating currents such as fast transients, single-pulse...
