“…In this section, these topologies are reviewed with the focus on their fault tolerance characteristics. Four main topologies are identified in the Energies 2022, 15, 5529 7 of 24 literature [3]: the parallel connected motors (PCM) and the series connected motors (SCM) topologies where one VSI feeds multiple motors and the shared leg (SL) and shared arm (SA) topologies, where an inverter leg or arm is shared between motors, respectively.…”

“…The higher switching frequency increases the losses and negatively impacts the reliability of the topology [53], thus switches with higher switching frequency rating and a faster controller must be used. Moreover, since only one switch may be closed in an inverter leg at a time, the sum of multiple motor currents must pass through it reaching up to n times the rated current of a motor for the outermost switches [3].…”

“…Furthermore, multi-motor systems pose challenges concerning energy management, coordinated control, cost, reliability and available space. Multiport inverter topologies are characterized with efficient energy processing, improved coordinated control, reduced cost, increased reliability, reduced size and potentially improved fail-operational characteristics [3]. These characteristics could be exploited to realize fault tolerant motor drives that meet the requirements of automotive XBW applications.…”

With vehicle electrification and employment of X-by-wire technology, mechanical systems are being replaced by motor drives which improve the efficiency and performance of vehicular systems. However, motor drives have a lower power density and reliability compared to mechanical solutions. Multi-motor drives have the potential of mitigating both these drawbacks. In this paper, a state-of-the-art review of multi-motor drives and their application to vehicular systems is carried out. Firstly, the case of multi-motor systems in automotive applications is laid out by presenting the different vehicular systems comprising multiple motors. Secondly, multi-motor drive topologies with improved power density, reliability and fault tolerance capabilities are thoroughly analyzed. Finally, the topologies are assessed and compared in the context of automotive applications. The assessment verifies that multi-motor drives allow for fault tolerant and cost-effective solutions that are suitable for automotive applications.

DC-Link Ripple Reduction for Parallel Inverter Systems by a Novel Formulation Using Multiple Space Vector-Based Interleaving Schemes

This paper proposes an analytical formulation-based minimization of DC link current ripples for interleaved parallel inverter systems. Parallel inverter systems find applications in multiple fields. The interleaved superposition of the DC link currents in these systems can potentially be adjusted to mitigate the overall harmonics consequently reducing the DC link capacitor size. To this end, a widely used approach in the literature is the Fourier analysis based on interleaving focusing on dominant harmonic mitigation. However, it leaves room for a generic analytical mechanism to provide time shifts leading to an optimal reduction in DC-link ripples. The goal of this work is to target this optimal reduction by utilizing an analytical mechanism. The paper presents an alternate way of DC-link formulation in terms of the piece-wise sinusoids of inverter output currents for space vector modulation-based systems. The formulation is then used to numerically optimize the interleaved shifts for minimum ripples. Moreover, in addition to the traditional concept of fixed time interleaving, a contemporary concept of sequence-based interleaving is utilized, which is anticipated to have more flexibility in the implementation and additional switching synchronism with PWM rectifiers for back–back converters. Therefore, the sequence interleaving has also been utilized in conjunction with the proposed ripple reduction methodology. Further, an underexplored area of using the combined impact of sequence and time interleaving has also been applied in this work. These interleaving methods are shown to provide significantly improved DC-link ripple mitigation, as compared to existing methods, using numerical assessment followed by simulations and experimental evaluation.
