SCALE Plug-and-Play Drivers – the Easiest Way to Build
Megawatt Converters
The following abstract points out the easy way to design megawatt
converters by using superior SCALE plug-and-play technology.
Furthermore, from page 9 you will gain greater insight into SCALE plug-and-
play drivers and will find must-read application notes.
Seven Steps to Success
Guide to designing a reliable megawatt converter:
1. Calculate the power dissipation of the IGBT Modules
First choose the IGBT module suited for your application and determine its particular
on-state and switching losses. These are used to approximate the size of heat sink
required.
Since high-power and high-voltage IGBTs have relatively high switching losses, the
switching frequency should be limited as much as possible.
2. Choose a suitable SCALE plug-and-play driver
When applying SCALE plug-and-play drivers, please note that these drivers are
specifically adapted to a particular type of IGBT module.
Therefore, the type designation of SCALE plug-and-play drivers includes the type
designation of the corresponding IGBT module.
These drivers are not valid for
IGBT modules other than those specified. Incorrect use may cause failure.
3. Design the power stack
When designing a power stack with high-current (high-voltage) IGBT modules, the total
DC link inductance should not exceed about 20nH...50nH (50nH…100nH).
SCALE plug-and-play drivers are specified and optimized to operate under such
conditions, resulting in superior dynamic behavior of the IGBTs.
