In recent years, OEMs have increased focus on development of Hybrid and Electric Vehicles (xEVs) in order to reduce vehicle emissions and dependency on conventional fuels. Energy storage systems are a critical consideration when formulating a strategy relevant to type of hybridization and vehicle. Though many battery technologies and different chemistries have matured, Lead-acid batteries still insist consideration because they have undergone their own remarkable evolution to keep up with the demand for greater efficiency. Given their inherent superior low temperature performance, standardized packaging boundary, less cost and better safety record, consideration bucket only hinges on overall cycle life and power performance and charge acceptance improvements. With advanced formulations leading to improvement in Lead batteries and advent of next Gen lead batteries, life and performance has been dramatically increased to enable serious consideration as a candidate for mild Hybrid applications. This paper will summarize the shortfalls of conventional Lead acid batteries and the advantages of Advanced Lead batteries. Typical merits and challenges faced in estimation of battery state and observations, improvement methods are also discussed in the context of Belt Starter Generator (BSG) based Low Voltage (LV) mild hybrid application in India.

Now-a-days multilevel converters are being considered for low voltage drives and electric vehicle (EV) applications. In EV applications, operating points vary dynamically causing deep variation in power factor and modulation depth. In this paper, a flexible modulation strategy is proposed for a three-level NPC inverter to fit-in such dynamic applications. Considering discontinuous modulation as the most efficient solution for such applications, the proposed modulation strategy provides the flexibility to shift its operating point seamlessly from sinusoidal PWM to generalized discontinuous modulation by allowing a small amount of additional low frequency oscillations. Moreover, a trade-off can be obtained to get the benefit of these two modulation patterns. Additionally, focusing on to the neutral point deviation problem of the NPC inverter, the proposed modulation strategy is capable of balancing two dc-link capacitor voltages effectively throughout the range. The effectiveness of the proposed scheme for a wide range of power factor and modulation index variations is studied through simulation by developing a MATLAB/SIMULINK model for a closed loop drives system. The efficacy of the proposed modulation scheme is validated through experimentation in a laboratory-scale prototype of NPC inverter with induction motor loads.

One of the main challenges in the development of hybrid electric vehicles (HEVs) is control and co-ordination of several power sources. Power electronic emulators for drive trains provide effective and economic ways to test and validate control strategies in real-time. This paper proposes a real-time emulator for parallel hybrid electric vehicles. The major mechanical and electrical parts of a typical parallel hybrid electric vehicle powertrain (the engine drive train and the motor drive train) is modeled mathematically and is emulated in real-time using power hardware-in-the-loop (PHIL). The individual sub-systems are modeled and locally controlled to maintain the required performance and control modes such as speed and torque. Real-time simulation was done in Matlab-Simulink and DS-1103 real-time controller and the results are presented. Voltage source inverters are used as power amplifiers to emulate the characteristics of the individual drive trains. The voltage source inverters are controlled by the same DS-1103 controller in rapid control prototype (RCP) mode. Experimental results with power hardware-in-the-loop emulator is presented for the validation of the proposed scheme.

This paper proposes FPGA based dual input converter (DIC) for battery charging applications of 3 kW. The proposed system gives an alternative way of fusing the sources of DC in the magnetic form, instead of combining in the DC electrical form, by the addition of magnetic flux that is produced in the transformer magnetic core that works on the principle of flux additivity. A detailed design and the operation of the proposed dual input full-bridge DC-DC converter has been completely evaluated and presented in this paper. A constant frequency phase shifted PWM switching strategy has been preferred for the generation of gate pulses using FPGA controller board. The simulation analysis of the proposed converter has been executed utilizing MATLAB Simulink environment. A prototype of 1.5 kW has been developed and hardware results are presented to validate the theoretical waveform of the proposed dual input full-bridge DC-DC converter.

In recent years, a number of industry applications increased with the use of advanced power electronics devices and frequency inverter fed induction motor. This study presents a highly reliable 3-phase dual-buck half-bridge shunt active power filter (DB HB APF) for the elimination of current harmonics produced by these non-linear loads. The dual buck inverter circuit effectually eliminates the undesirable “shoot-through” occurrence ensues in conventional inverter circuit. The fuzzy based id-iq control strategy with adaptive hysteresis has been adopted to generate the reference compensating current. For validation, the proposed topology is implemented in the OPALRT LAB uses OP5142-Spartan 3 FPGA.

Z-source inverters are very popular in recent times because of their inherent capability to step up/down the input voltage. This concept can be extended to multilevel inverter. As compared to multilevel inverter, two level Z-source inverter has several drawbacks like high filter size, poor performance in terms of THD, efficiency etc. This paper presents a Z-source integration into modular multilevel converter. Switched inductor cells are used as Z-source network because they exhibit better flexibility and reduced passive element count to achieve desired gain. Furthermore, the analysis of proposed inverter is done in discontinuous current mode(DCM) which signifies that even higher gain can be achieved as compared to continuous current mode(CCM). To implement the control scheme full shoot through or upper shoot through/ lower shoot through technique are developed and compared. For performance calculation, the proposed inverter is simulated using MATLAB/Simulink platform.

Fuel economy and emissions are of utmost importance in today's automotive industry. One of the highly known and practiced methods to satisfy both the needs is powertrain electrification. To cater the future needs of meeting emission norms and improved Fuel economy, the automotive manufacturers intend to convert the already existing conventional IC engine based vehicles, into hybrid vehicles or BEVs. Prior to the conversion, determination of economic viability and interpretation of the benefits from electrification are necessary, to estimate the worth of the time, money and resources spent on the process. This research studies the possible benefits from various functions of electrified powertrain such as regenerative braking, torque assist, load point shift for higher engine efficiency, etc. and additional penalties due to electrification such as weight addition, increased electrical load, etc., and analyses the role of each function in improving the Fuel economy of the vehicle. It also presents the break-even point analysis for various factors in electrification such as weight added due to electric components, scope of torque assist, etc. to achieve target economic benefit. Also, the research studies benefit of powertrain electrification from the end user's perspective.

The Integrated Starter Alternator (ISA) needs to cater for a very wide range of torque and speed, in both motor and generator modes and in different functionalities, such as engine starting, alternator, regenerative braking and torque boost. Furthermore, each of these functionalities, being dependent on the drive cycle, means that determining the optimal ISA torque-speed characteristics is a challenging problem. In this paper, a Monte-Carlo simulation has been reported to find the most frequently operated regions in the torque-speed plane of an ISA, using stochastic drive cycles. This has been used to determine the optimal torque-speed characteristic to inform the ISA design specification. In turn, this gives a more robust coverage of different driving patterns compared to a conventional driving cycle-based design
