The concept of electric vehicles has become an emerging trend for the last few years owing to their hefty returns. This article also becomes a part of the emerging electric vehicle technology replacing the conventional vehicle. This article presents the illustration of the hybrid electric vehicle employing the solar and fuel cell as the sources of electric vehicle. It is also involved in the proposal of Maximum Power Point Technique (MPPT) for controlling the output of the sources. It also presents the utilisation of different types of controllers like Proportional Integral Derivative Controller (PID), Fuzzy Logic Controller (FLC) and Neural Network (NN)-based peak power point technique for following the maximum power of the sources. This evaluates the performance of different controllers-based power point technique in terms of voltage, current, power, response time, torque ripples and efficiency of the system and aims to improve the system performance by 10%. The proposed hybrid electric vehicle structure has been simulated and results are demonstrated using MATLAB/Simulink.

Simulation and analysis of three-phase parallel inverter using multicarrier pulse width modulation such as phase disposition (PD), phase opposition disposition (POD) and alternate phase alternate disposition (APOD) are presented in this article. In this proposed work, reduced active switching count, transformers, single DC input, a high degree of modularity and redundancy are key merits and also suitable for renewable energy systems. The proposed three-phase five-level multilevel inverter with single DC source using a three-phase transformer is controlled by multicarrier pulse width modulation schemes. To generate switching pulses for five-level inverter, four carrier signals can be compared with a reference signal. The performance of the inverter is examined by using PD, POD, and APOD by modulation index (MI) starting from 0.4 to 1. Furthermore, the over-modulation region is also analyzed in this paper. The effectiveness of the system is analyzed in terms of total harmonic distortion by varying the MI of the inverter. The simulation results are verified through MATLAB/Simulink.

In this paper recently proposed three-phase multi-level inverter topologies and modulation techniques are discussed. Multilevel inverter topologies (MLIs) are more utilized in high-medium power applications due to their several benefits such as less harmonic contents, less power dissipation on power switches and less electromagnetic interference (EMI) outputs. For harmonic elimination, the chosen switching method for inverter control is also a plays a significant role to produce the ideal output voltage. In this, mainly three different topologies are categorized in MLIs; those are diode clamped, flying capacitors and cascaded H-Bridge. Similarly, different H-Bridge inverter topologies and control techniques also discoursed. In this paper mainly focused on three-phase inverter using a single DC source and transformers. The various carrier based modulation techniques such as phase disposition (PD), Phase Opposite Dispostion (POD) and Alternate Phase Opposite Dispostion (APOD) have been invstigated through MATLAB/Simulink environments.
