What is the full form of RBSOA with reference to IGBT?

The correct answer is option 4):(Reverse bias safe operating area)

Concept:

• RBSOA with reference to IGBT is Reverse bias safe operating area
• The Reverse Bias Safe Operating Area (RBSOA) is the range of current and voltage that an IGBT can be used without deterioration or destruction during the IGBT turn-off.
• The IGBT is developed by combining the characteristics of a BJT and a MOSFET
• The on-state losses of an IGBT are lesser than a MOSFET
• The switching frequency of IGBT is very high compared to BJT.
• So it is faster than BJT.
• The IGBT contains a parasitic thyristor
