Meeting demands for the portable welders in terms of switching and conduction losses, our TRENCHSTOPTM 5 effects best performance compared to other IGBT on the market for one-phase inverters. Dependent on the switching behavior you can chose between different options. For three-phase welding Infineon recommends the 1200V High Speed3. Typical applications can be found in hobbyists in building constructions, workshops, car repair shops.
As every switch needs a driver, Infineon offers a broad range of dedicated drivers for Welding applications. We outline here one of our high voltage, high speed IGBT drivers with Coreless Transformers technology, EiceDRIVER™ Compact 1EDI20I12AF.
If your application requires a higher welding current, we recommend our well-known 62mm 1200V dual IGBT modules with the IGBT2 fast technology for high frequency switching. Our 62mm & 34 mm portfolio stands for flexibility, optimal electrical performance and for highest reliability. Typical applications these IGBT modules can be found are iron industry as well as the Industrial Automation.
Depending on the particular welding market, Infineon offers different diodes as secondary side rectification:
The Rapid 1 power silicon diodes fill the gap between the SiC diodes and emitter-controlled diodes for up to 80A/650V.
The housing less welding diode is a high reliable and robust device specifically for the requirements in the automotive and metallurgical welding applications up to 20kA/600V.
