Comment la thermographie peut être utilisée pour garantir un design optimisé et fiable – du premier coup, à chaque fois

When designing an inductive component, an essential consideration is a change in temperature. Heat can impact the performance and efficiency of the component in operation, with aging, endurance, and life span affected detrimentally.

Within the component, changes in core magnetisation and power losses from the winding cause temperatures to increase. The maximum operating temperature and current are closely related and are key parameters of a component’s specification. The maximum DC current is expressed as the rated current (𝐼𝑟), also known as the nominal current (𝐼𝑛). The design’s viability is initially determined through calculations and simulations, with physical testing taking place at the prototype stage.
