Q value, refers to the measurement of the main parameters of the inductor device. Refers to the inductor in a certain frequency of AC voltage work, the presented inductance and its equivalent loss resistance ratio. The higher the Q value of the inductor, the smaller the loss, the higher the efficiency. The quality factor of the inductor is related to the DC resistance of the coil wire, the dielectric loss of the coil bobbin and the loss caused by the core and shield.
Know the Q value of the relevant factors, but how do we improve the quality factor in the design of it?
On the relationship between the magnetic loss and Q value Now more stringent power supply design requirements, which requires us to each problem must be carefully analyzed and calculated for the calculation of magnetic loss is generally a simple calculation based on the size of the core and the associated loss curve Simple calculation but the actual work, with a core winding different ways, with the same magnetic core winding the same way the different degree of tension, but bring a different temperature rise and so on, but has been a magnetic The relationship between magnetic loss and Q value is seldom mentioned. It is simply that the Q value has a large magnetic loss, but the Q value is related to which factor, and it is not mentioned in practice.
