Partial Power Processing Based Bidirectional Converter for Electric Vehicle Fast Charging Stations

Abstract

This paper focuses on the design of a charging unit for an electric vehicle fast-charging station. Electric Vehicle is turning into a real alternative to conventional combustion-based vehicles due to their reduced greenhouse emissions. The conventional system experiences harmonic distortions, losses and takes more time to charge. To overcome these problems, new methods and techniques are established here. With the help of a bidirectional-based converter, electric vehicle charging stations offer quick charging. When using a three-phase supply, phase voltage is given to the suggested converter. In conventional type converters, harmonic distortions are inherent; however, we can lessen voltage distortions by employing bidirectional converters. When tested with a prototype model featuring the suggested converter, the voltage ripple factor is quite low. Phase-shifting pulse width modulation is the topology employed in this procedure. The output voltages are controlled by a precise and simple algorithm. We can also use artificial intelligence gadgets to improve the circuit in the future. By comparing the input and output voltages in the feedback system, we can eliminate both steady-state and transient errors. The charging stations implemented in various areas are used effectively for efficiently charging Electric vehicles. The number of components is reduced compared to traditional converters and thus increasing the efficiency of bi-directional converters with less cost. This charger is also verified for fluctuations in power supply and supply voltages with higher magnitudes. The proposed charger gives us improved power factor and efficiency.
