3. OBJECTIVE
The main objective is to integrate by using“Site-of-action”integration of power
electronics technique to hybrid vehicles.

4. INTRODUCTION
● Hybrid Vehicles is nothing but a vehicle having two or more power sources.
Example:-Internal combustion engine and an induction motor.
● The term Integration means connecting power electronics with mechanical system
● First hybrid vehicle was developed in 1900 by Ferdinand porsche.

5. WHY HYBRID VEHICLES RATHER THAN EVs
● The main drawback of Electric Vehicle is it cannot run with higher speeds compared To ICE vehicles.
● EV is only economical for short distance travelling.
● Electric Vehicle takes more time to charge.
● So to travel for longer distance and to achieve higher speeds we use ICE and induction motor in vehicle.
● ICE has more power density than Induction motor in EV.

6. ROLE OF POWER ELECTRONICS IN HYBRID VEHICLE
● used for conversion(AC-DC/DC-AC)
● used for closed loop control of motor
● advancement of efficiency and performance of vehicle
● control of fuel loss in Internal Combustion Engine

7. HYBRID ELECTRIC VEHICLE(HEV)
● Vehicle consists of ICE engine and 3 Phase induction motor.
● For short distance travelling, vehicle run in EV mode (runs with induction motor).
for longer distances the vehicle run in ICE mode.(runs with ICE engine).
● Induction motor runs the vehicle wheels and battery gives supply to the motor
● Battery is charged by regenerative braking.

11. PLUG-IN HYBRID ELECTRIC VEHICLE (PHEV)
● The structure of PHEV is similar to HEV but PHEV has charging plug and a large battery storage
compared to HEV.
● In HEV, the battery can charged by regenerative braking. Whereas in PHEV there is a charging plug to
charge the battery thus it is called PHEV.

14. POWER ELECTRONIC DEVICES USED IN HYBRID VEHICLES
● Bi-directional Z-source Nine Switch Inverter(BZ-NSI):- It converts DC voltage of battery to AC and fed to
the motor
● Bi-directional DC-DC converter:- It converts DC voltage of battery to DC to eliminate the distortion in DC
battery voltage.
● Alternator rectifier (AC-DC converter): It converts AC power from alternator to DC power because battery
can only store DC power.

15. RATINGS OF POWER ELECTRONIC DEVICES

18. BATTERY RATINGS
Nickel-Metal Hydride Battery (Ni-MH):
Capacity: 20,000mAh
Voltage:12V /490V

19. RATINGS OF INDUCTION MOTOR

20. DRAWBACKS OF POWER ELECTRONICS
●Power electronics devices are bigger in size. Consumes more space
●costly due to high power ratings.
●devices can produce harmonics.
●Control, optimization and management is difficult because of multiple power sources.

21. SOLUTION
●using Silicon Carbide (SiC)and Gallium Nitride(GaN) power semiconductor devices which has thermal
conductivity and lesser in size.
●ElectroMagnetic Interface (EMI)filters,which reduces harmonics in power electronics.

22. FUTURE SCOPE
● Higher Integration of levels for inverters ranging upto 300kW
●Power electronics devices temperature upto 400V
●SiC and GaN devices

23. CONCLUSION
Power electronics plays an crucial role for hybrid vehicles they are important to increase the over all
efficiency of hybrid vehicle.and reduces the pollution of the vehicle.
