DC/ DC Step-Down Converter

The course ”Step Up / Step Down Converter” deals with how electric vehicles can increase high voltage battery voltage to the sometimes much higher voltages required for the electric motor and also shows how the high voltage can be in turn reduced to low voltage to run the 12 volt battery and run the vehicle's electrical and electronics system.
