I need to design 3power supply has the following specifications
1-input from 84 to 305vac and output is 24VDC 200watt .is sepic converter followed by llc will be OK from the point of efficiency
2-input from 84 to 160 vac and output is the same as above .Using pfc followed by llc is ok?
3-input voltage from 160 to 305vac and has the same output .Using sepic followed by llc will be more efficiency
Can you please suggest some others topologies more efficiency.
