A 400W (1kW Peak) 100A Electronic Load Using Linear MOSFETs
https://www.electronics-lab.com/400w-1kw-peak-100a-electronic-load-using-linear-mosfets/
Kerry Wong built a 400W/100A electronic load using linear MOSFETs. He writes: I bought a couple of IXYS linear MOSFETs (IXTK90N25L2) a while ago to test their capabilities when used as electronic load, and the result was quite impressive. So I decided to build another electronic load using both MOSFETs. As you can see in the […]
How to test a power supply or solar system?
https://www.electronics-lab.com/how-to-test-a-power-supply-or-solar-system/
Electronic loads, programmable and with a recovery function are the best choice for dynamic testing simulating real conditions. Usually you don´t test your power supply and you assume it is working well with your equipment. But what if not? Sometimes your equipment fails without any evident reason and it might be because your power supply […]
