6 FAQs about [Igbt photovoltaic inverter explosion]

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.
