* 1.) Around 2% efficiency gain when the output load is below 40% of the full load. 2.) Hold Up time can be increased ~ 30% from the existing 6800 power supply. 3.) 420V bulk capacitor value can be reduced, and also PFC boost ripple current can be reduced; therefore, the boost inductor core size may
