Teardown of a 2.1 kW peak solar inverter, the Sunmaster / Mastervolt XS2000. It is based on TO-247 MOSFETs for voltage regulator and isolation. From the datasheet, it is actually only able to deliver 1500 Watt to the mains connection. Do you know about this secret place for MOSFET and IGBT lovers? Maybe you are […]

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
A teardown of a Migatronic Pilot 1800, a combined TIG & stick welder. TIG is short for Tungsten Inert Gas and refers to the tip of the welding handle, which is made out of tungsten. A inert gas comes from the handle, to surround the tip and ensure no air is near the welding bath.

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

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
