“…The switching losses were analytically calculated, starting from the measured E on and E off , and determined from device characterization, which can be defined as the function of V DD , I DS and R g . Under the assumption that V DS = 400 V and R g = 10 Ω maintain constant values, the switching energies can be exclusively expressed as functions of I DS , (7). Their behavior can be depicted using a generic curve-fitting mathematical tool, where the weight coefficients k 1 , k 2 , k 3 and k 4 have been determined at different junction temperatures of T j .…”

“…However, maintaining the charging voltage at the typical value of 400 V would necessitate increased current ratings for charging cables, leading to amplified system power losses. Some automotive manufacturers are exploring solutions involving an 800 V DC bus to achieve faster battery-charging times [5][6][7][8][9]. However, this approach presents technical challenges related to current electric powertrain technologies, especially semiconductor technologies utilized in electric traction inverters.…”

The main aim of this work is to present a step-by-step procedure to model and analyze the power loss distribution of three-level Gallium Nitride (GaN) inverters. It has been applied to three distinct three-phase three-level voltage source inverters utilized in electric traction drives: Active Neutral Point Clamped, Neutral Point Clamped and T-Type Neutral Point Clamped. The proposed analytical power loss modelling, combined with an equivalent representation of the electrical machine proved to be a viable solution to achieve a time-saving and low computational burden simulation platform, leading to satisfying accurate results. This has been confirmed by comparing the results carried out from the simulations of a 110 kW permanent magnet synchronous motor drive and those determined by considering a simplified circuital representation based on the proposed analytical power loss modelling.

“…To mitigate this problem, an electric vehicle battery pack typically consists of a combination of cells interconnected in both series and parallel. EV battery packs typically have a voltage of 300-800 V [26], which defines the number of series-connected cells. The battery pack's voltage and energy determine the pack's capacity, defining the number of parallel-connected cells.…”

Considering the need to optimize electric vehicle performance and the impact of efficient driveline configurations in achieving this, a brief study has been conducted. The drivelines of electric vehicles (EV) are critically examined in this survey. Also, promising motor topologies for usage in electric vehicles are presented. Additionally, the benefits and drawbacks of each kind of electric motor are examined from a system viewpoint. The majority of commercially available EV are powered by a permanent magnet motor or single induction type motors and a standard mechanical differential driveline. Considering these, a holistic review has been performed by including driveline configurations and different battery types. The authors suggest that motors be evaluated and contrasted using a standardized driving cycle.
