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.
