2 kVA Solar Inverter Teardown, the Mastervolt XS2000

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 […]

IGBT Gate Drive Transformer (GDT) Design, Construction and Test

A guide on how to calculate gate drive transformer, how to wind gate drive transformers and test gate drive transformers. Gate drive transformers are also called GDT for short. The most important aspects is insuring low leakage inductance, no core saturation and having enough peak drive current available for your MOSFETs or IGBTs. This video

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
