Interior Permanent Magnet (IPM) motors are strengthening its candidature as traction motor in Electric Vehicles (EV) because of their advantages like high power density, extended field weakening and high efficiency. IPM motor being a complex control problem with inherent rotor saliency characteristic, extensive characterization on regenerative dynamometer is required for traction applications. This paper proposes a virtual characterization methodology for IPM motor using 2D Finite Element Analysis (FEA). The bench and vehicle test results confirmed the dynamic performance of IPM motor drive with acceptable accuracy.

Plug-in electric vehicle (PHEV) is emerging as most environmental friendly and widely used transportation system in developing countries. The integration of PHEV to existing grid infrastructure requires substantial modifications to be carried out in context of load scheduling, grid reliability, peak to average demand ratio (PAR) and energy cost. Recent studies are focussed to meet such requirements using multi-objective optimization methods. The optimization technique aims to minimize demand, energy cost and increase availability of PHEVs to charge or discharge by generating suitable scheduling vector. This paper proposes separate charging and discharging scheduling vector for fulfilling the utility aim to reduce PAR and also benefit the PHEV owner by reducing overall energy cost.

This paper introduces a Two-input Switched Inductor Capacitor Hybrid Buck-SEPIC DC-DC converter (TISICHBSC) topology useful for various DC power applications. The converter falls into a category of electrically coupled Multi-input DC-DC Converters (MICs) which can provide adequate bucking of voltage even at higher duty ratios. As it offers excessive bucking the converter uses additional energy storage elements, so it is of sixth order family MIC. It is a modified converter topology of earlier proposed Two-input Hybrid Buck SEPIC (TIHBSC) converter. A 36/12 V to 24 V, with power capacity of, 100W prototype is considered to validate the proposed concept. The controllers are designed in discrete domain based on Quantitative feedback theory (QFT) to obtain the robust performance. The theoretical analysis is validated through simulations.

The regulatory standards concerning safety of the occupants, pedestrians & the vehicle have been made stringent in recent years. This priority of safety has led to the introduction of Antilock Braking System (ABS) and Electronic Stability Control (ESC) systems in vehicles. The presence of an electric motor, the key powertrain member in electric vehicles (EVs), makes the implementation of safety systems very effective and challenging at the same time. This is effective, since the torque response from the motor is instantaneous, aiding in ultra-low response time from & to Electronic control unit (ECU) leading to faster vehicle control. However, the challenge is the synchronization of an off-the-shelf available ABS/ESC hardware to the existing EV control architecture. In addition, low weight of the vehicle requires the control and actuators to be very fast for stable operation. The toggling of the regenerative brakes and the intervention of the ABS based on vehicle conditions needed a handful of design & testing iterations. The paper explains about ABS & ESC system implementation & its testing details in a light-weight electric vehicle.

Torque ripple is an inherent disadvantage that inhibits the usability of Switched Reluctance Motors (SRM) in industrial and automotive applications. Torque Sharing Function (TSF) is a promising strategy for the torque ripple reduction in SRM drives. The major bottleneck of TSF based methods is that the actual phase current fails to track the reference current generated by the TSF controller during the demagnetization of each phase. This current tracking error will result in torque ripple. An online compensation technique is proposed in this paper to compensate this torque ripple. The effectiveness of the proposed compensation technique is established through simulation results. A study on the impact of TSF based methods on the stator radial force, which is the key source of structure-borne noise in SRM, is also presented in this paper.

Dynamic Partial Reconfiguration (DPR) of Field Programmable Gate Array (FPGA) offers the members of benefit across multiple industries. Partial Reconfiguration (PR) has been supported by Xilinx for many generation of devices. Hardware portion of the device function is dynamically modified by partial reconfiguration technique by downloading full and partial bitstreams. In this paper some specific regions are reconfigured of the FPGA with new functions during run time while remaining areas become static during this time. Xilinx PlanAhead provides graphical environment for PR which reduces the board space, changes the design in the field and also provides low power consumption.

In recently developed marine propulsion systems, diesel-electric generators (two for propulsion and one small generator for auxiliary load) are employed as power sources. Optimal sizing of these generators results better fuel use efficiency and lesser emission. Tugboat load cycle consists of loitering, transit and assist mode which is estimated an average engine load of around 20% of bollard pull (BP) capacity. A 60T BP tugboat system is considered in this research along with variable speed technology and analysis is made on sizing of generators and its effect on fuel consumption. From the results, it is observed that 3.1% fuel saving is possible in proposed system in comparison with a referred electric tugboat system. Techno-economic study is also carried out on the proposed system.

High voltage stress, harmonic as well as subharmonic distortions are observed in the pulse width modulated voltage source inverter fed squirrel cage induction motor drive. It result losses in the motor, damages the winding insulation, and create electromagnetic interferences etc. As a result, it reduces the efficiency of the motor drive and shortens the life of the motor. Generally, sinusoidal LC filters are placed in between the inverter and the induction motor to smoothen the nonsinusoidal waveform to address these issues. This paper proposes a new method of designing sinusoidal LC filter based on the filter, inductor ripple current and the reactive power compensation of the induction, which basically reduces the voltampere rating of the inverter and effectively improve the overall efficiency of the drive. The newly designed filter and the filters designed by the standard methods, have been tested with the rotor flux oriented controlled induction motor and its performance have been compared.

Hybrid Electric Vehicles with different voltage levels, powertrain structures, and vehicle variants are driving OEMs to develop and maintain multiple software systems including functions like torque assist, regenerative braking, generation and start-stop. Development of such complex software systems includes challenges like reusability, maintenance, variant management, complexity, testability and redundancy of these functions. This situation provides the opportunity for OEMs to explore common software system with acceptable effort, calculable risk and even time-to-market. Furthermore, the OEM has the possibility of being more flexible when selecting suppliers for base software and hardware and reducing dependency of a single system supplier. One of the main goals for the OEM is to improve containment of product/ process complexity, risk in addressing the challenges of complex software system and ensure it is hardware independent for seamless porting into various supplier hardware. Presented in this paper is a creative way of utilizing AUTOSAR with Advanced Software Developing Methods to scale this complex software system and optimize the business trend.
