Description

technical field [0001] The invention belongs to the technical field of electronic testing, and in particular relates to an adjustable reactor and an equal-step adjustment method thereof. Background technique [0002] Reactor is a basic electronic component (device), and it is often necessary to change different inductance values ​​in actual electronic products. The common method to adjust the inductance value is to change the position of the magnetic core or change the winding turns through the slider (brush). However, these methods of adjusting the inductance have low precision and are not suitable for digital adjustment control. The multi-tap inductor can be digitally controlled, but when the inductance adjustment range is wide and the resolution is required, the number of taps is large, and the inductance of each tap of the multi-tap inductor is difficult to control and the inductance is difficult to manufacture. as attached figure 1 As shown in the figure, the series c...
