Plug & Play in Power Electronics Designing a proper circuit to drive a given IGBT module
by Dr. Martin Schulz, Infineon Technologies, Bodo's Power Systems, Feb 01 2009
Focus:
Infineon's MIPAQ serve is a six-pack IGBT module with built in drivers, transformer isolation, logic-level inputs and digital temperature measurement. This article describes the construction and operation of this module, its features and benefits for designers including the designer's ability to treat the module as a "plug-and-play" device. The article describes the advantages of Coreless Transformer Technology over optocouplers as a means of isolation, particularly as a means for reducing IGBT dead time in inverter applications. A 3-D graph shows output voltage ratio as a function of dead time and switching frequency.
What you’ll learn:
- How to understand the operation and benefits of "plug-and-play" IGBT modules
- How to reduce dead time in inverter designs by using IGBT modules with transformer-based isolation
