In this schematic i use Sg3525 and 2 mosfet IRF3205 with transformer from old PC power supply.
The max power can reach 350W.
I use Eagle software for make Schematic.

1: Connect the output with Load.
2: Connect input with battery. I use 12V battery
Be Careful with high voltage, electric shock will kill you do not touch any output component
