Design and Implementation of Measuring High-precision Inductance Based on a Single-chip Microcomputer

Wang Yan-jvu

Abstract

Inductance is one of the components widely used in circuit and its precision can effect directly the performance of the circuit. The method for measuring the value of inductance in this paper adopts L-T circuit,which can translate value of inductance to oscillation cycle and transmit value of inductance to CPU to measure and process data through buffer circuit and filter circuit. The circuit can also show directly the measuring result. In this paper, not only the design of hardware and software is presented, but also the cause of measuring error is analyzed.
