CMOS 4047 is the capital basic of this baby voltage advocate which transforms a 12V dc into 220V ac. 4047 is acclimated as a astable mutivibrator, at pins 10 and 11 will accept a balanced ellipsoidal arresting wich is amplified b 2 Darlington transistors and assuredly ability the accessory braid of mains agent ( 2×10V / 60VA ).
At the capital braid terminals will get 220V. With the advice of P1 the achievement frequnecy can be adapted amid 50Hz to 400Hz. Although this is not allotment of any able dc ac converters it can be acclimated absolutely able on some home appliances.
