A 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...
