how to transform into variable power

1- regulator UC28025 and MOSFET control


2- before hacking

If you need hight voltage ( >20v) you must add winding to transformator and change output capacitor (16V max).  Three output MOSFET near connector must be removed also : they are H5N03LA witch support only 25V. replace them by a lead short-circuit. Pictures  will help.
