Whereas older power MOSFETs would share internal power, newer MOSFETs grab the current, causing thermal runaway. Using a thermal camera and an oscilloscope to look at the voltage and current internal to the MOSFET, we can understand how a hot spot develops on its surface.

Output power is one of the most critical parameters of laser cutting machines which could decrease over time due to wear and tear or user errors. Therefore, diagnosing it by using appropriate power monitoring instruments and techniques is easy and saves time and money for your business.
