650 V TRENCHSTOP 5 D2Pak IGBT: Improving performance of a portable welding machine power supply using SMD on IMS
Application note for using Infineon 650V TRENCHSTOP 5 D2Pak IGBTs in portable welding machines with SMD-on-IMS assembly to improve efficiency and reduce system size.
Overview
This application note describes a 4 kW portable welding machine power supply design based on a half-bridge converter topology. It demonstrates the transition from through-hole TO-247 packages to surface-mounted D2Pak (TO-263-3) IGBTs using the IKB40N65EH5. The document details the implementation of Insulated Metal Substrate (IMS) technology to reduce stray inductance, lower junction temperatures, and improve power density. It includes technical guidance on IMS material selection (copper foil, dielectric, and base plate), thermal system design, and assembly guidelines for TRENCHSTOP 5 IGBTs in SMD packages.
Use Cases
- Portable welding machines (MMA, TIG, MIG, MAG)
- Uninterruptible power supplies (UPS)
- Photovoltaic inverters
- EV charging stations
- High-frequency power converters
