This paper deals with the measurement and intermittent performance analysis of 12-switch NPC inverter driven PMSM drive in electric vehicle application. The objective of this paper is to demonstrate the multilevel inverter driven PMSM drive with carrier-based space vector modulation (CBSVM) strategy in MATLAB environment with reduction of total harmonic distortion and torque ripple. The method currently used for constant speed and torque is field oriented control (FOC) in permanent magnet synchronous motor (PMSM). The simulation results are presented based on inverter output and motor parameters such as stator and rotor current, speed and torque of PMSM. After validation of results, the proposed FOC-based 12-switch neutral point clamped inverter (TSNPCI) driven PMSM drive is found suitable for electric vehicles due to speed, torque response, better control performance, good dynamic response and lower costs. The hardware and simulation results are validated and matched for the effectiveness of the drive.

Conventionally powered cars produce noise from the combustion engine and exhaust system. Electric cars do not have an internal combustion engine, and therefore no intake, exhaust or gearbox, so noise is generated mainly as a result of variable electromagnetic forces accompanying the conversion of electrical energy into mechanical energy. All vehicles equipped with both conventional and diesel engines also emit noise as a result of the interaction of the tyres with the road surface and from the air flowing over the body (aerodynamic noise). The article measures noise inside and outside an electric vehicle. The measurements were carried out in city and highway traffic conditions. Research has shown that the main source of noise is the interaction of tyres with the road surface and aerodynamic noise.

While driving a car, the comfort of the driver is crucial. By considering seated concerns for the drivers' comfort and health, the exceptional and skilled designers' concept should be successful. On a standard car seat, the bottom and upper body sections, in addition to the head support, are significant. The seat's vibration-attenuation design is crucial to the comfort of the driver. Components of the human body are sensitive to lower frequency vibration, and problems occur when they are frequently subjected to it. An individual's health will be harmed by prolonged vibration exposure. In this work, the finite element method with experimental modal analysis has been used to estimate and evaluate the natural frequencies in the driver's seat which affect to the human body. Since it has been shown that some of these frequencies coincide with the ones that are dependent on the human body, the natural frequencies associated with a driving seat that affect the human body can be changed without modifying the design.
