Here a 3v & 12v battery have been used to boost DC for running heavy DC Motor with low input power.
Its a voltage booster circuit which involves 1:1 transformer and the boosting part is achieved from the inductive switching cycle.
Power transistor used is 1351 npn and resistor is 1k ohm at 5w.
Its better to use MJE13009 for better performance.
