1 Introduction
1.1 Description of the AIT Smart Grid Converter
AIT Smart Grid Converter is a four phase four wire converter designed for today‘s
Smart Grid and emerging Low Inertia Micro Grid applications. With seamless
transition between Grid Forming, Off-Grid and Grid Supporting modes, its highly
reliable cooling concept designed to ensure long life time, broad range of
connectivity options: IEC61850, ModBus TCP, SunSpec, and modular and
stackable concept of increased power handling capability, the AIT Smart Grid
Converter presents a perfect Smart Grid fit.
