“…Some powertrain architectures employ dual VSIs for traction motor and generator machines [94]. A DC-DC boost converter is also introduced in certain designs between the energy storage element and the inverter [94]- [96]. Since EVs operate in light load conditions for a considerable amount of time, applying a DC-DC converter to vary the DC-bus voltage could be a viable option to ensure efficient operation under light loads.…”

Mobile platforms cover a broad range of applications from small portable electric devices, drones, and robots to electric transportation, which influence the quality of modern life. The end-to-end energy systems of these platforms are moving toward more electrification. Despite their wide range of power ratings and diverse applications, the electrification of these systems shares several technical requirements. Electrified mobile energy systems have minimal or no access to the power grid, and thus, to achieve long operating time, ultrafast charging or charging during motion as well as advanced battery technologies are needed. Mobile platforms are space-, shape-, and weight-constrained, and therefore, their onboard energy technologies such as the power electronic converters and magnetic components must be compact and lightweight. These systems should also demonstrate improved efficiency and cost-effectiveness compared to traditional designs. This paper discusses some technical challenges that the industry currently faces moving toward more electrification of energy conversion systems in mobile platforms, herein referred to as E-Mobility, and reviews the recent advancements reported in literature. INDEX TERMS Battery technology, fast charging, high-frequency magnetic materials, high-power-density converters, hybridized battery systems, more electric powertrains, wireless charging. I. INTRODUCTION Next-generation mobile platforms, ranging from handheld devices, mobile robots, and drones to automobiles, aircraft, and ships, require small, light, cost-effective, and longer operating energy systems to meet more aggressive mission profiles [1]-[3]. At the same time, most of these mobile platforms are moving toward more electrification, i.e., electrified-mobility (E-Mobility), if not fully there already. E-Mobility, herein, refers to more electrification of energy conversion systems in mobile platforms. E-Mobility opens new opportunities to meet the required energy system objectives, while also presenting new challenges.

“…The main advantage of this design is that the UC is utilized to the best possible extent. On the other hand, the drawback of this design is that it requires two full bridge converters, thus resulting in an increase in the overall size and cost of ESS [18,19]. In continuous decelerating mode ( Figure 9) the DC/DC converter goes into buck operation, thereby transferring the energy from the UC to the battery [16].…”

This paper introduces a new topology using a multi-source inverter with the intention of reducing the battery current and weight, while enhancing the battery life and increasing the driving range for plug-in electric vehicles, with the combination of a battery and an ultracapacitor (UC) as storage devices. The proposed topology interconnects the UC and battery directly to the three-phase load with a single-stage conversion using an inverter. The battery life is considerably reduced due to excess (peak) current drawn by the load, and these peak load current requirements are met by connecting the ultracapacitor to the battery, controlled through an inverter. Here, the battery is used to cater to the needs of constant profile energy demands, and the UC is used to meet the dynamic peak load profile. This system is highly efficient and cost-effective when compared to a contemporary system with a single power source. Through a comparative analysis, the cost-effectiveness of the proposed energy management system (EMS) is explained in this paper. Energy and power exchange are implemented with an open-loop control strategy using the PSIM simulation environment, and the system is developed with a hardware prototype using different modes of inverter control, which reduces the average battery current to 27% compared to the conventional case. The driving range of electric vehicles is extended using active power exchange between load and the sources. The dynamics of the ultracapacitor gives a quick response, with battery current shared by the ultracapacitor. As a result, the battery current is reduced, thereby enhancing the driving cycle. With the prototype, the results of the proposed topology are validated.

“…An innovative topology was proposed in 2013 [186], using an eight switch inverter to interface a three-phase induction motor and a single-phase ac electrical grid. An innovative topology termed as multisource inverter was recently proposed for plug-in hybrid EVs, aiming to connect multiple dc sources to the same ac output though a single power conversion stage [187,188]. 6.2 Integrated battery chargers: the electric motor perspective Concerning electric motors, switched reluctance motors have been gaining interest due to their constructive simplicity, low size and weight, and low cost.…”
