A method for fast characterization of power efficiency in induction heating processes

In English

Författare

Summary, in English

A method for fast and precise measurement of effciency in induction heating processes is evaluated and tested. The method, based on thermal imaging is presented with advantages and drawbacks based on results from coupled transient simulations and from experimental results. The experiments are performed using two different induction heating platforms, equipped with high quality measurement equipment, including a thermal camera, capable of streaming 16 bits radiometric data for image recording on a computer. Post-processing of the recorded data, including compensation of camera position and integration of electrical and thermal properties is explained and the results presented with pictures of each step. Also some basic knowledge of radiometric measurement of temperature is described to better understand the possibilities and to avoid unnecessary pitfalls. Guidelines of how to choose the best equipment or setup forms the conclusion of the article, providing a method that can be used also for other applications.
