(1) The average efficiency is an assumption for a typical application where the power supply is loaded with 25% of the nominal load for 25% of the time, 50% of the nominal load for another 25% of the time, 75%
of the nominal load for another 25% of the time and with 100% of the nominal load for the rest of the time.
