Abstract
The invention discloses an adjusting method of an adjustable inductor and an inductance value. The adjusting method of the adjustable inductor and the inductance value includes a hollow coil (3) and a pair of magnet yokes (4). The magnet yokes (4) can be freely inserted in the coil respectively from two ends of the hollow coil. The adjusting method of the adjustable inductor and the inductance value further comprises a first clamping plate (2) fixedly connected with one magnet yoke and a second fixing clamping plate (6) fixedly connected with the other magnet yoke. The first clamping plate is mutually fixedly connected with the second clamping plate through a connecting column (5) made of nonmagnetic materials. The connecting column is arranged to be hollow in the axial direction. A heating device (1) is arranged in the connecting column. The distance between the first clamping plate and the second clamping plate is set, thus a gap of opposite ends of the two magnet yokes is set. The initial inductance value of the adjustable inductor is obtained. The connecting column is heated by the heating device, the length of the connecting column changes, thus a gap of the magnet yokes is adjusted. The inductance value of the adjustable inductor is changed. The adjusting method of the adjustable inductor and the inductance value has the advantages of being simple in structure, mature in technology, high in reliability, low in cost, capable of achieving long-distance continuous electronic control adjustment at the same time and the like.
Description
Technical field
The present invention relates to variable inductor, be specifically related to the control method of a kind of variable inductor and inductance value.
Background technology
Existing common variable inductor is generally to lean on the permeability of the regulating winding number of turn and adjusting inductance magnetic conductive loop to change inductance value.The mode limitation of the regulating winding number of turn is very large, and in adjusting inductance magnetic conductive loop, the mode of air gap amount size is widely used.The air gap regulative mode has two kinds of mechanical adjustment and circuit adjustment usually, and mechanical adjustment is to adjust yoke position (a kind of high-power adjustable inductor as disclosed in Chinese patent CN201110130871.1) by man-operating mechanism or automechanism; Circuit adjustment is mainly to produce one group of controlled magnetic field by circuit to regulate (a kind of controllable impedance as disclosed in Chinese patent CN201210144165, the disclosed numerical control variable inductance of CN201010563886).The man-operating mechanism regulative mode can not be realized automation, the automechanism regulative mode complex structure, cost is high, volume weight is large, degree of regulation is general.The circuit adjustment mode is more applicable for AC inductance, and for the application in DC circuit owing to having increased dc magnetization, the working range of inductance magnetic circuit is reduced, the electromagnetic performance of magnetic core can not take full advantage of, efficient is lower, causes the increase of inductance volume and complex circuit, cost high.
