IGBT is nothing but a switch,we can use even MOSFET instead
of IGBT.but the thing is that,IGBT has faster switching
speed,otherwise called the operating frequency,hence the
performance and efficiency of the UPS system gets improved

Answer / ramesh

Good

Answer / dipankar ghorai

To increase the operating frequency of the UPS we may use
it.

Answer / ramesh

High switching speed with high impedance in a single component with low expensive inside of BJT & MOSFET.
    High-current and high-voltage bipolars are available, but their switching speeds are slow, while power MOSFETs may have high switching speeds, but high-voltage and high-current devices are expensive and hard to achieve.so this difficulty shortouted by IGBT
