“…To reduce this number, the designer can leverage on guidelines and models that describe a relation between the design levers and their effect on the design criteria. In literature on IMMDs, the effect of using interleaved PWM carrier waves on the DC link ripple current has been extensively covered [10][11] [12]. However, for other design levers, especially the DC link architecture circuit topology, this relation is less well documented.…”

This article describes a holistic DC link architecture design method that considers the end-application of the drive and its corresponding constraints e.g. the maximum battery ripple current for a battery-supplied inverter. Also, the levers that are available to comply with the design criteria are presented e.g. the use of interleaved carrier waves. This holistic approach will result in a feasible and performant Integrated Modular Motor Drive from an application point of view. Finally, a platform is presented that was developed for feasibility and performance assessment of various DC link architectures obtained from the holistic design approach. The platform comprises a fifteen phase integrable modular motor drive for an Axial Flux Permanent Magnet Synchronous Machine. It allows non-intrusive reconfiguration of the DC link architecture and implementation of various control strategies and interleaved PWM schemes.

To meet the demand for increasingly high power density in electric drives, the concept of a so-called integrated modular motor drive has emerged. The machine is composed of multiple identical modules, which receive individual control signals for multiphase control, to reduce unwanted stator current harmonics. Each module is equipped with its own power electronic converter, which is integrated in the machine housing. This integration imposes strict constraints on the dc-link capacitor design. To reduce the dc-link current ripple, and hence relax the design constraints on the dc-link capacitor, without compromising the possibility to eliminate unwanted stator current harmonics by means of multiphase control, a new interleaving strategy is proposed in this article. The n modules of the machine are split into p subgroups of m modules for interleaving, while the n-phase control is preserved. An analytical model, simulations and experimental results are provided for a 4 kW test setup, confirming that multiphase control can be combined with interleaving. As a result, both the stator current harmonic distortion and the dc-link current ripple can be reduced simultaneously.

Through its new technology the ISCAD system provides up to 300 kW with a safe-to-touch 48 Volt battery. This results in a high-performance drive that is intrinsically electrically safe. The novel machine design requires new concepts for power electronics, control systems, and integration strategies. Further degrees of freedom yield to challenges and even more important to possibilities for all kinds of applications. The innovation of the design will be explained and adjustments for power electronics and control will be worked out. The focus of this paper is the 3 rd generation of Intelligent Stator Cage Drive (ISCAD) prototypes. This first integrated and compact prototype has been used to re-equip a Geely Emgrand EV. The entire system and the mentioned process are described in detail. In addition, the in-house designed 48 V battery is highlighted. Simulations and measurements give an overall demonstration of the potential and the current status of the drive.
