DC to AC Converter

IC 4047 monostable multivibrators of low power compiles a a real heart good to simple changer which can give output of AC 245V from entering DC 12V. For this applying of course IC connected in monostable mode. Square wave signal which simentris there is at output of Q and Q1 and strenghtened by a couple of transistor darlington ( T1 and T2) and then is given to secondary circumference trasformator low voltage ( 2 X 10V 60VA). Output of AC 245V then available at transformator primary winding. Output tension frequency can be various between 60 and 400 Hertzs by arranging potenhometer trimmer p1.
