Z-Source Inverter for Energy Management and Vector Control for Electric Vehicle Based PMSM

Abstract

Electric vehicles have gained considerable attention recently due to the ever increasing demand for a viable alternative to the current fossil fuel-dependent modes of transportation. These automobiles are reliant on power electronics to generate the energy required for the motor. Traditional converters, namely the V-source (VS) and C-source (CS), are vulnerable to EMI noise, their main circuits cannot be interchangeable and they are either a boost or a buck converter. Therefore, their output voltage is strictly higher or lower than the input voltage. In an effort to negate these drawbacks, new inverters such as the Z-source were conceptualized. This work aims to study the applicability of the Z-source in the traction chain of an electric vehicle in order to feed a permanent magnet synchronous motor (PMSM). The latter is controlled with field oriented vector control reinforced with a backstepping technique in an attempt to ensure tracking ability and robustness. Energy management is also supported in this article in an effort to optimize the performance of the electric vehicle under different operating conditions. The simulation results show the effectiveness of the proposed system in enhancing the energy management of the vehicle, in addition to its simplicity which can facilitate an eventual implementation using a DSP or a Dspace platform.

Artificial Neural Networks Based Power Management for a Battery/Supercapacitor and Integrated Photovoltaic Hybrid Storage System for Electric Vehicles

“…The use of a hybrid energy storage system requires a robust energy management technique to provide proper energy flow in all of the electric vehicle components [21], which is accomplished using an artificial neural networks strategy. This strategy is one of the suitable methods to deal with the internal relations of a complex model because of its high nonlinearity, large amounts of data-parallel processing, and high robustness [22].…”

Modelling, Simulation and Analysis of Indirect Space Vector Control of Electric Vehicle Driven by Permanent Magnet Synchronous Motor with Fuzzy Controller

“…Nonetheless, several experts and researchers have presented alternative techniques for EVs in selection of motor, inverter and control mechanism. The PMSM could be powered by sinusoidal PWM inverter, Z-source inverter and multilevel inverter [6,7]. Due to less complexity in design and control mechanism SVPWM inverter is employed in this study and also the output voltage of SVPWM inverter is 15% greater relative to sinusoidal PWM inverter.…”
