Electric Vehicles (EV) is now assumed to be one of the green transport modes. Generally speaking, EV will further usually create a low-carbon market over the forecast period. Switched Reluctance (SR) motors possess new perspectives throughout this field, as they have no permanent magnets; just high-silicon steel as well as copper windings have been mandated. SR motors have been driven by asymmetric bridge converters with a significant number of switches, leading to higher power loss and negative torque current. Even when SR motors have several advantages, the acoustic noise affected by radial vibrations and torque ripples it seems to be additional drawbacks that need to be compensated. This paper proposes to achieve this six-phase multilevel converter. This article demonstrates the designed to operate theories and models of a six-phase multilevel converter for a 12/8 SRM drive. In the designed motor drive, the banks of battery have been used to connect the power source of the generator directly to maintain multilevel voltage as well as to operate the generator. The capacitor would be used to boost the DC-link voltage for battery-driving functions. The proposed topology reduces the torque ripple and ensures a smooth response of the speed. The circuit is simulated and analyzed using the software MATLAB.

This paper focus on the simulation and hardware analysis of a diode clamped multilevel inverter (DCMLI) fed direct torque control (DTC) permanent magnet synchronous motor (PMSM) drive in electric vehicle (EV) application. DTC-PMSM drive is more used for torque and speed control. The existing DTC PMSM drive consists of torque and flux hysteresis comparators and suffers from variable switching frequency and torque ripples. These problems can be solved by using carrier-based space vector modulation (CBSVM) about torque and flux. In this proposed approach a DCMLI fed 4 poles, 0.5 HP DTC PMSM drive system is designed and simulated using carrier-based CBSVM. Simulation and experimental implementation are carried out in MATLAB environment and AVR Microcontroller respectively. The simulated performances are studied in steady-state and transient conditions for varying load, speed, and torque. The results of the DTC-PMSM drive system using CBSVM show that the proposed method can effectively reduce the torque ripple and maintain a constant speed and also improved driving performance of drive for electric vehicle applications.

The effectiveness of a permanent magnet synchronous motor (PMSM) drive managed by an automatic voltage regulator (AVR) microcontroller using field oriented control (FOC) with space vector modulation (SVM) and a diode clamped multilevel inverter (DCMLI) is investigated. Due to its efficacy, FOC would be widely implemented for PMSM speed regulation. The primary drawbacks of a 3-phase classic bridge inverter appear to be reduced dv/dt stresses, lesser electromagnetic interference, and a relatively small rating, especially when compared to inverters. PMSMs have a better chance of being adopted in the automotive industry because of their compact size, high efficiency, and durability. The SVM idea states that an inverter's three driving signals are created simultaneously. Using MATLAB simulations, researchers looked into incorporating a DCMLI with a resistive load on an AVR microcontroller. Torque, current, and harmonic analysis were evaluated between the SVM and the inverter-driven PMSM drive in this research. In comparison to the prior art, the proposed PMSM drive has better speed and torque management, less output distortion, and less harmonic distortion.
