converter
Re-consider AC-grids in the light of
Renewable engergies
Switch mode power supplies
Demonstrate
5% less power consumption
7% cost reduction for solar power
DC Components
Current - / Voltage - / Power-Sensors
Based on magnetoresistance
Galvanically isolated from measured circuit
High accuracy & low power consumption
Semiconductor Switches
Development of MPT-IGBT technology
Next improved generation w.r.t. losses vs. switching speed
DC Grid Demonstration
Office Building Test Bed at Fraunhofer IISB
Safe environment to test systems & concepts
Extended measurement facilities

DC Power Switches
Electro-mechanical switches
Classical solution with special adaption to
arc-extinction
Arcing is the main
challenge in switching
off DC nets
Hybrid Switches
Combine speed of semiconductors with low loss
of mechanical switch
