Problems solved by technology

[0004] Based on this, it is necessary to address the problems that traditional impedance detectors have large volume and heavy weight, are only suitable for laboratories, and cannot be portable
In addition, the traditional portable impedance detector only calculates the impedance by the ratio of voltage and current, the calculation accuracy is low, the calculation amount is large, the speed is slow, and it cannot keep up with the speed of radio frequency, and it is not suitable for the field of radio frequency power supply. Provide a Impedance detection method, impedance detector and system

Abstract

The invention relates to an impedance detection method, an impedance detector and a system, and the method comprises the steps: obtaining the electric signal data of a to-be-detected circuit; correcting the electric signal data to obtain voltage real part data, voltage imaginary part data, current real part data and current imaginary part data; and obtaining load impedance data according to the voltage real part data, the voltage imaginary part data, the current real part data and the current imaginary part data, thereby realizing impedance detection of the to-be-detected circuit. By improving an impedance processing algorithm, the calculation precision is improved, the calculation amount is reduced, the calculation efficiency is further improved, meanwhile, a traditional high-cost and large-size hardware circuit does not need to be adopted, the size of the impedance detector can be further reduced, and the impedance detector can be more conveniently carried for measurement while being suitable for radio frequency power supply application occasions.

Description

technical field [0001] The invention relates to the technical field of impedance detection, in particular to an impedance detection method, an impedance detector and a system. Background technique [0002] Impedance measurement technology is an important part of electronic measurement technology. It has the characteristics of non-invasive, simple to use, and low complexity. It is widely used in biomedicine, electrochemistry, industrial control, power grid control and other fields, and can meet the measurement needs of various parameters. Currently, there are three main types of impedance detectors that can be used in the field of RF power supplies: LCR measuring instruments, impedance analyzers, and network analyzers. [0003] In the process of implementation, the inventors found at least the following problems in the traditional technology: the existing impedance detector has problems such as large volume and heavy weight, which are only suitable for laboratories and cannot...
