Power supply design Schematic and pcb-2

We need to design a power supply with 3 output voltages.

1- input source is universal 100-240 AC input 50/60hz

2- output is 28 volt DC regulator 6 amp

3-12 volt DC 2 amp fixed

4-5 volts DC 3 amp regulated .

5- isolated voltage between 28 and (12-5) is 1500 v RMS.

6- the design is opay UL and EMC standard.

The PCB will be smaller as much as we can.

the 28 is isolated from 12 to 5 ( 12 & 5 have the same GND).
