“…Among different ML inverter topologies, the dual-2L inverter is particularly suitable and effective for EVs, being equivalent to a 3L inverter but with a traditional, cheap, and reliable three-phase inverter structure [3][4][5][6][7][8]. In this case, the motor is supplied from both the open-winding ends by two standard 2L inverters, as shown in Figure 1b.…”

“…Although the dual inverter structure has been intensively examined in the last decades [3][4][5][6][7][8][10][11][12], no studies are available concerning the amplitude of current ripple, except for [6], but there the RMS value was of interest. In particular, the analysis of the output current ripple amplitude in three-phase 2L inverters has been recently introduced in [13][14][15].…”

Abstract:The standard solution for the traction system in battery powered electric vehicles (EVs) is a two-level (2L) inverter feeding a three-phase motor. A simple and effective way to achieve a three-level (3L) inverter in battery-supplied electric vehicles consists of using two standard three-phase 2L inverters with the open-end winding connection of standard three-phase ac motors. The 3L inverter solution can be usefully adopted in EVs since it combines several benefits such as current ripple reduction, increment of phase motor voltage with limited voltage ratings of the two battery banks, improvement in system reliability, etc. The reduction in current ripple amplitude is particularly relevant since it is a source of electromagnetic interference and audio noise from the inverter-motor power connection cables and from the motor itself. By increasing the inverter switching frequency the ripple amplitude is reduced, but the drive efficiency decreases due to the proportionally increased switching losses. In this paper the peak-to-peak ripple amplitude of the dual-2L inverter is evaluated and compared with the corresponding ripple of the single-2L inverter, considering the same voltage and power motor ratings. The ripple analysis is carried out as a function of the modulation index to cover the whole modulation range of the inverter, and the theoretical results are verified with experimental tests carried out by an inverter-motor drive prototype.

Electric vehicles (EV) are getting more commonplace in the transportation sector in recent times. As the present trend suggests, this mode of transport is likely to replace the internal combustion engine (ICE) vehicles in near future. Each of the main EV components has a number of technologies that are currently in use or can become prominent in the future. EVs can cause significant impacts on the environment, power system, and other related sectors. The present power system can face huge instabilities with enough EV penetration; but with proper management and coordination, EVs can be turned into a major contributor to the successful implementation of smart grid. There are possibilities of immense environmental benefits as well, as the EVs can extensively reduce the greenhouse gas emission from the transportation sector. However, there are some major obstacles for EVs to overcome before replacing the ICE vehicles totally. This paper is focused on reviewing all the useful data available on EV configurations, energy sources, motors, charging techniques, optimization techniques, impacts, trends, and possible directions of future developments. Its objective is to provide an overall picture of the current EV technology and ways of future development to assist in future researches in this sector.

The predictive torque control (PTC) scheme for four-level open-end winding permanent magnet synchronous motor drive (OEW-PMSM) is introduced in this article, owing to its simple and intuitive algorithm. However, the classical PTC-PMSM drive performance mainly depends on the weighting factors (WF) used in cost function (CF) and its selection is a cumbersome process. Hence, a new approach for eliminating these WFs is proposed for four-level PTC-OEW-PMSM drive without dropping its benefits in classical PTC method. The torque and flux objective errors are considered as two individual CFs and evaluated with all available voltage vectors (VVs). Then, the set of VVs corresponding to the ascending orders of CFs magnitudes is considered as separate VVs groups. The common VV present in both these VV groups represents the minimised torque error, flux error and treated as the optimal VV for the next control period. As a result, the monotonous flux WF tuning is no more required. The limited VVs strategy is also proposed for reducing the computational burden of PTC. The proposed four-level PTC method is initially tested in MATLAB/ SIMULINK and experimentally verified on PMSM drive.
