Special Issue Information

Dear Colleagues,

We are currently witnessing great leaps forward towards electrified transportation, in order to meet the global call for reduced greenhouse gas emissions. The recent advances in electric drives are poised to substantially impact the evolution of next-generation electrified transportation systems. These advances in electric drives are motivated by the imperative to meet the increasingly stringent requirements of modern transportation systems (e.g., torque and speed requirements of electric vehicles), and are enabled by advances in machine design, power electronic switches, and electric drive controls. Electric vehicles, as well as light and heavy rail traction systems, are examples of where innovations in electric drives can make a tangible impact on electrified transportation. This Special Issue aims at archiving some of the recent advances in both the physical design and controls of electric drives, in the context of transportation electrification. Examples of the topics of interest include, but are not limited to: Design and control of electric vehicle drives, applications of new switching devices in electric drives, and electric drive control for recuperation of regenerative braking energy in electric vehicles and trains. Furthermore, topics of interests in the area of reliability and condition monitoring of electric drive systems in electric vehicle’s powertrain include, but are not limited to:

  1. Online diagnosis and prognosis of faults in closed-loop inverter-fed motors for transportation electrification.
  2. Finite element analysis co-simulation of inverter-fed electric motors to characterize and identify signatures of motor faults.

Energy storage technologies are developing rapidly, and their application in different industrial sectors is increasing considerably. Electric rail transit systems use energy storage for different applications, including peak demand reduction, voltage regulation, and energy saving through recuperating regenerative braking energy. In this paper, a comprehensive review of supercapacitors and flywheels is presented. Both are compared based on their general characteristics and performances, with a focus on their roles in electric transit systems when used for energy saving, peak demand reduction, and voltage regulation. A cost analysis is also included to provide initial guidelines on the selection of the appropriate technology for a given transit system. Full article

In wide voltage range applications such as electric vehicles (EVs) onboard charging, conventional frequency modulated LLC topology has its intrinsic limitations. Its frequency span is extremely wide and the soft switching feature might get lost. To address this issue, this paper proposes a novel LLC resonant converter. The pulse width and frequency hybrid modulation are adopted to narrow down its switching frequency span. The operating principles, circuit modeling, and the design methodology are presented. A 1 kW rated prototype has been built to realize an efficient power flow between the 400 V DC bus and 200–440 V battery pack. The designed prototype validates the effectiveness of the proposed topology and modulation method. 96.8% peak efficiency is measured for the constructed experimental prototype. Full article

In this paper, a new three-level boost converter with continuous input current, common ground, reduced voltage stress on the power switches, and wide voltage gain range is proposed. The proposed converter is composed of a three-level flying-capacitor switching cell and an integrated LC2D output network. The LC2D output network enhances the voltage gain of the converter and reduces the voltage stress on the power switches. The proposed converter is a good candidate to interface fuel cells to the dc-link bus of the three-phase inverter of an electric vehicle (EV). A full steady-state analysis of the proposed converter in the continuous conduction mode (CCM) is given in this paper. A 1.2 kW scaled-down laboratory setup was built using gallium nitride (GaN) transistors and silicon carbide (SiC) diodes to verify the feasibility of the proposed converter. Full article
