Week 4 Session 5
Various applications of Power converters in an Electric vehicle
Assuming the provided car battery to be a 48V
1. Vehicle Headlight
Voltage requirement -12V
Battery source - 48V
Converter used - DC-DC converter (Chopper)
We use Chopper for stepping down the voltage
We can use Buck converter
2. Horn system
Voltage requirement -6V
Battery source - 48V
Converter used - DC-DC converter (Chopper)
We can use Buck type converter for stepdown
3. Auxillary Battery
Voltage requirement -48V
AC Supply source - 230V
Converter used - AC-DC converter (Rectifier)
4. AC cooling system
Voltage requirement -120V
Battery source - 48V
Converter used - DC-DC converter (Chopper)
We can use Boost type converter for stepup
5. Fuel Pump system
Voltage requirement - 12.5 – 13.0 volt
Battery source - 48V
Motor - DC
Converter used - DC-DC converter (Chopper)
We can use Buck type converter for stepdown
6. Car wiper system
Voltage requirement - 13.5 volts, 60 Hz
Battery source - 48V
Induction Motor
Converter used - DC-AC converter (Inverter)
7. Car Radiator fans, Power Windows
Voltage requirement - 12 volt
Battery source - 48V
Motor - DC
Converter used - DC-DC converter (Chopper)
We can use Buck type converter for stepdown
The purpose of the motor is to rotate the blades and cause them to move air.
8. Power Steering
Voltage requirement - 12 volt
Battery source - 48V
brush dc motor
Converter used - DC-DC converter (Chopper)
We can use Buck type converter for stepdown
