Option 4 : 1, 2 and 3

DC to DC converters (DC Choppers):

A dc chopper converts dc input voltage to a controllable dc output voltage.
For lower power circuits, thyristors are replaced by power transistors.
Choppers find wide applications in dc drives, subway cars, trolley trucks, battery driven vehicles, etc.
