A look at a bag of IGBTs and MOSFETs that I quickly salvaged from industrial electronics. Found in induction cookers, solar inverters, welding machines, car and battery charges. It can also be other common high power electronics with switching inverters. Discussion of salvaging IGBTs/MOSFETs: https://highvoltageforum.net/index.php?topic=2117.0 These TO-247 IGBTs can be used in a DRSSTC Tesla …
Teardown of a Sirio 10000P solar inverter designed in Italy and made in Taiwan. A extremely heavy and well built power house. Full of TO-264 sized IGBTs and a giant single PCB layout for the inverters. To watch more teardown videos with articles full of high resolution pictures, check out the complete list of equipment …
This Sedecal SHF-330, with HF meaning High Frequency, was originally a 37.5 kW x-ray high voltage generator. It later received an upgrade, to a Sedecal SHF-530, which is a 50 kW 500mA x-ray high voltage generator. This x-ray generator comes in 3 different versions. Line powered drawing all power directly from mains, 20-50 kW. Capacitor …
