The advancement in power electronics converters to improve the efficiency and reliability of vehicular system is elaborated. In this paper, the role of power electronics converters in electric vehicle is elaborated. Provides an extended support to researchers who dealing with same areas.
In the reverse direction, the energy from the battery or ultra-capacitor is injected into the AC grid line in the plug-in electric vehicle. Power electronic converters play a vital role in the conversion process from grid line to traction motor and in the reverse direction.
Hence, power electronics converters are responsible for the advancement in EVs (Chan, 2002). This paper will elaborate on the state-of-the-art of the PECs in the battery, hybrid, fuel cell, and plug-in electric vehicle systems and compare the associated advantages and disadvantages of the existing PECs for theze vehicular systems.
Another EV subsystem where DC link capacitors are found is the inverter in motor drive circuits (shown in Figure 3). The inverter converts DC power from the battery to three-phase AC power to drive the traction motors during acceleration, and then converts AC power back to DC during braking.
The voltage controller controls the power flow from the battery in/out directions. In PEV, the bidirectional DC-DC converter plays a vital role in controlling the bidirectional flow of energy. It operates in step-up mode during V2G mode and acts as a step-down converter in G2V mode.
General electrical structure of EVs. In a recent vehicular system, a three-phase converter acts as an inverter during fuel, battery, split and combine mode whereas rectifier in regenerative mode. The selection of converter mode is sophisticated and controlled by the traction controller unit.
