Problems solved by technology

In physical experiments, the AC bridge method is often used to measure inductance. Although this method is relatively accurate, the structure of the bridge for inductors with different quality factors is different. At the same time, the AC bridge needs to be repeatedly adjusted to achieve a precise balance in the experiment, and the actual operation is more troublesome. , students have certain difficulties in completing independently

Description

technical field [0001] The invention belongs to the field of physical experiment measuring instruments, and relates to a measuring device for parameters of electronic components, in particular to an oscillometric inductance measuring device. Background technique [0002] Inductors are basic electronic components that are heavily used in electronic equipment. Inductance, referred to as inductance, is an important physical parameter of an inductor. In physical experiments, the AC bridge method is often used to measure inductance. Although this method is relatively accurate, the structure of the bridge for inductors with different quality factors is different. At the same time, the AC bridge needs to be repeatedly adjusted to achieve a precise balance in the experiment, and the actual operation is more troublesome. , students have certain difficulties in completing independently. Contents of the invention [0003] The technical problem to be solved by the invention is to pr...
