How to Measure Component and PCB Temperature During Power Electronics Operation

Hi guys
The world of power electronics is becoming increasingly important.
Is there any way to measure component and PCB temperature during power operation?
Thanks to all,
John

Hello. There are many solutions:

1) On a real circuit, you can use a thermometer and measure the different temperatures. Then report the temperatures on the PCB figure, on the computer, and color accordingly. You will get a heat map.

2) You can use a heat gun or an infrared thermal camera, to read the various temperatures

3) In simulation, you can use SOAtherm models, which give support for the thermal characteristics of some power components (with LTspice)

4) Some software gives the ability to measure operating temepratures (for example, in MicroCap)

5) You can simulate the temperature of a single component using FEN software (For example, PrePoMax). You have to create a 3D model of the component, to scale, provide the correct materials, the correct ambient temperatures, and the powers involved.

Hello John,

You can use integrated temperature sensors such as thermistors or semiconductor temperature sensors. These sensors can be placed directly on the components or PCBs to measure their temperature in real-time. The data can then be read using a microcontroller or a data acquisition circuit.

Hi John,

Measuring component and PCB temperature during power operation is essential for monitoring and ensuring the proper functioning and reliability of electronic devices.
There are several methods to accomplish this like infrared thermometer, thermocouples, IC temperature sensors, thermal imaging camera, digital temperature sensors.
