What factors are related to the inductance of air-core inductors?And what is its calculation formula?1. Calculation formula of inductance of air-core inductor: First use paper to make a small cylinder, and then wind an inductor coil on the cylinder to make an air-core inductor. Calculation formula of air-core inductor: LmH)=(.08DD.NN/(3D+ 9W+10H) 1. This can calculate the number of turns of the winding inductor: Number of turns = [Inductance* { (18*turn diameter (inch)) + (40 * turn length (inch))}] ?turn diameter (inch) ) Number of turns = [8.116 * {(18*2.047) + (40*3.74)}] ?2.047 = 19 turns The number of turns can be calculated based on the above points: Number of turns = [Inductance* { ( 18* Turn diameter (inch)) + (40 * loop length (inch))}] ? loop diameter (inch) number of loops

High-frequency electronic transformers are electronic transformers with high operating frequency, generally higher than 20kHz.The precise definition is an electronic transformer with a high operating frequency. Generally, the operating frequency is higher than 20kHz, which is high frequency.The definition of high-frequency electronic transformer is very clear, but it has been misled by some opinions expressed by some domestic experts.In order to return to the true nature of high-frequency electronic transformers, it is necessary to clarify the concepts of transformers, electronic transformers, and high-frequency electronic transformers in order to eliminate those misunderstandings.First, let’s find out what is a transformer?A transformer that works on the principle of electromagnetic induction means that alternating voltage is applied to the primary winding of the coil to generate alternating magnetic flux, and an output voltage is induced in the secondary winding, thereby transmitting energy, converting voltage (or signal), and electrically insulating The role of isolation.To produce electromagnetic induction, alternating voltage must be applied to the primary winding. It is impossible to have a transformer with DC voltage as the working power supply.That kind of DC voltage
