Power4re - Integrated moisture measurement system in inverters - Fraunhofer IZM

The inverters used for grid feed-in in solar parks and frequency converters in wind turbines are exposed to particularly challenging operating and environmental conditions. In power4re, material, process and structural optimizations as well as protection concepts for inverter components were developed. A unique field database from wind energy applications, fault components and access to photovoltaic and wind energy systems for field measurements were available for this purpose.

Derived offer for the industry:
- Avoidance of downtimes through preventive maintenance strategies based on integrated condition assessment
- Monitoring of moisture- and field-induced degradation
o Comb structures as condition indicators (SIR measurement)
o Sensors can be integrated directly on the driver circuit board
o Low costs and minimal space requirements thanks to standard technology and small number of components
