一种新型数控可变电感的研究与设计

针对现有电路中电感元件的电感量难以数字化调节的问题,研究并实现了一种新型的,可以对电感量进行数字化调节的“数控可变电感”.这一新型“数控可变电感”主要利用了不同电感之间的互感特性,通过数字电位器和相应的信号调制使电路控制附属电感上的电压大小,进而改变主电感对电信号的相应特性,最终对外表现出电感量的数字化可控特性.实验证明,该可变电感参数稳定,且具有较高的电流通过能力.

Analysis and Design of A New Numerical Control Variable Inductance

In view of the problem of the inductance element in existing circuit with its inductance value hardly to be digital regulated,this paper analyses and achieves a new ’NC variable inductance ’ which could process the inductance value with digital regulation.This new ’NC variable inductance ’ mainly uses the characteristics of mutual inductance between the different inductances to regulate the voltage value of the affiliated inductance by digital potentiometer and some corresponding signals,then change the corresponding characteristic of the electrical signal with main inductance,and eventually show the digital controlled characteristic for inductance value.The experiment shows that parameters of the variable inductance are stability,and it has high capacity to let the current flow through.
