Scrap Yard IGBTs and MOSFETs from Solar Inverters, Welding Machines and Induction Cookers

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 […]

Where To Get “Free” TO-247 IGBTs and MOSFETs

A look at a box of IGBTs and MOSFETs that I have salvaged from household electronics like microwave ovens, induction stoves, solar inverters, welding machines, car and battery charges and other common high power electronics with switching inverters. The TO-247 IGBTs can be used in a DRSSTC Tesla Coil using the free half- and full-bridge

Fujifilm FCR XG-1 X-ray Laser Module Teardown (Part 2 of 3)

Part 2: Teardown of the laser scanner module from a Fujifilm FCR XG-1 x-ray image scanner / digitizer. Also known as Computerized Radiography (CR), it fulfills the job of scanning a x-ray exposed image plate. It uses a laser beam to extract each pixel illumination with a photo multiplier tube setup. It can scan 72
