A major advantage of operating a power semiconductor as a switch rather than in its linear region is?

  • AHigher conversion efficiency
  • BGuaranteed zero electromagnetic interference
  • CInfinite switching frequency
  • DNo need for protection circuits
Report an error
Correct Answer: A. Higher conversion efficiency
Explanation: Switch-mode operation ideally keeps either voltage or current small in the device, reducing power dissipation compared with linear control.
