Degradation Signature Characterization Validation with Field Data Predictive Modeling Degradation Signature Characterization The data from the characterization of parts before and after stress testing will be analyzed for useful fingerprints that indicate degradation and remaining lifetime. One approach is to apply the characterization results to simulations to look for corresponding changes in behavioral parameters of [...]
Thermal Management Subsystem Inverters Capacitors Switches Thermal Management Subsystem Thermal management of inverter systems and internal components is critical for ensuring lasting performance reliability. Research is currently being carried out to more accurately characterize inverter components and system topologies of varying scales. This work includes: Thermal/fluid phenomena of internal inverter components, and their impact on [...]
As scientists and engineers improve the durability of photovoltaic (PV) modules, the inverter system, which converts the harvested energy into power usable by the grid, becomes the next emerging challenge in the reliability of the PV system. Addressing these issues represents a difficult task to both the PV and power systems communities for the following [...]
