6 FAQs about [Photovoltaic inverter replacement igbt explosion]

What are IGBT based power switching devices?

These inverters dominantly comprise of power semiconductor based switching devices. Insulated Gate Bipolar Transistor (IGBT) based power switching devices are mostly utilized for inverters in GCPS . The IGBTs in inverters are exposed to diverse and rigorous working conditions and therefore, they are susceptible to failure conditions .

Why is IGBT used in a central inverter?

The IGBT is usually used to the central inverter topology as it can carry high current capacity with several fluctuations (overshoot and undershoot) due to the radiation disturbances because of the clouds cross or sandy windstorm. However, the investigated work can be implemented to other inverter applications which used MOSFET.

Why do IGBT failures occur?

Furthermore, most IGBT failures occur because of the temperature rising which leads to high thermal stress . The disadvantages of these publications are that there is no clear data analysis.

Does central inverter failure affect PV power plant availability & Roi?

This paper reviewed several publications which studied the failures of the PV power plant equipment’s and presented that the central inverter failures rate is the highest for the PV power plant equipment’s which affected negatively in both PV power plant availability and ROI.

What are the most common inverter components failures?

According to the relative frequency of inverter components failures reported in , both software/firmware failures and IGBT failures are the most frequent failures. Furthermore, most IGBT failures occur because of the temperature rising which leads to high thermal stress .

Does DWT based fault feature mining work for grid connected PV inverters?

An ANN based FDL employing DWT based fault feature mining for grid connected PV inverters is proposed , which incorporates thermal overstress and wear out failures in IGBTs using MATLAB/PLECS integration. This work develops two classifiers, which are able to work in both component failure and degradation conditions.
