MOSFET, PC PSU Power Supply, ARDUINO, Heating Element

Hello House,

I am trying to carry out a research experiment on a switched-mode power supply. I want to heat up the power mosfet/shcottky diode to see it behaviour and if it will fail. I am looking at a setup with arduino and a heating element over the switched mode power supply.

I would be waiting for any suggestions to execute this experiment. Thanks

Hi,
What are we looking at in the picture, can you put some labels on the image so we know what we are looking at?

What voltage and wattage heater are you going to use.

You will need the heating element close to the schottky diode, or a MOSFET which is it?
Just heating up the power supply will not ensure you are testing the diode, but possibly the whole powersupply.

Can you please tell us your electronics, programming, arduino, hardware experience?

Is this a school/college/university project?

Thanks.. Tom... :smiley: :+1: :coffee: :australia:

Attached is a well-labeled picture of my experiment.

The idea I have is to position the heating element across the heat sink as I wont get direct access to the diode/mosfet since it is packaged device.

I am looking at 220v heater with a 200 to 240 degrees capability. The diode on the power supply datasheet says it can fail at 150 degrees celcius.

Hi,
Wouldn't it be easier to remove the diode and load it up, and apply heat directly.
Your measurements would be more accurate as you only have the device to heat and measure parameters.

@TomGeorge This is a school project. I don't really have much experience on electronics, programming and arduino but I am willing to learn as possible. My major is mechanical but I have been saddled with a research path on electronics that I need to excel in.

You are right Tom but the whole idea is to take measurement while the diode is in the packaged devices. I can buy the diodes and subject them to heat but I want the measurement taken from a packaged device.
