When we talk about electric car we often have in mind that electric vehicle work on battery and electric motor thereby one important component that we often forget is power electronics. Power electronics plays the major role in electric and hybrid cars. Power electronics form the control center and brain of the electric drive.
POWER ELECTRONICS
The power electronic technology is becoming popular over the last 20 year. The purpose of the power electronic technology is to control the power using electronic devices. These electronic devices are use in the convert power into different Power modes as per the need of the electric drive system. Power electronics divides electrical engineering into three areas of specialization. Electronics, …show more content…
The high voltage battery supplies the direct current to power electronics. The power electronics convert the direct voltage into an alternating voltage and supply the electric motor/generator with three electrical phases via the three wires (U, V and W).
ADVANTAGES OF ELECTRIC VEHICLE Some of the main advantages of electric vehicle are follows:
• Electric vehicle run smoother and quitter as compared to combustion engine.
• Electric drive motors have a high degree of efficiency of up to 96% compared with internal-combustion engines that have an efficiency of 35–40%.
• The drive train design is simpler because vehicle components like the transmission, clutch, mufflers, particulate filters, fuel tank, starter, alternator and spark plugs are not required.
• The high-voltage battery can be charged at home, in a car park and by using any accessible sockets. The blue charging connector on the vehicle and on public charging stations has been standardized across Germany and is used by all manufacturers.
• Apart from the reduction gearbox on the electric drive motor, the electric vehicle does not require any lubricating oil.
