This article proposes a dc-link structure that can be integrated with circumscribing polygon modular integrated drives. A generic design methodology is provided for this structure, which combines dc-link capacitors and bus-bar without increasing the diameter of the integrated structure. The influences of the bus-bar parasitics on dc-link waveforms are evaluated using electromagnetic finite element method (FEM) models, and electromagnetic and computational fluid dynamics (CFD) models are developed to ensure reliable operation in high ambient temperatures.
In this article, a dc-link structure feasible for integration with the circumscribing polygon modular integrated drives is proposed. The proposed dc-link structure combines both the dc-link capacitors and the bus-bar together and integrates them with the machine and the converter modules without increasing the outer diameter of the integrated machine/converter structure. A generic design methodology for the proposed dc-link structure is provided and applied on a reconfigurable 15 stator coils concentrated winding axial flux machine for all its possible phase configurations. The design methodology presented in this article involves the determination of the required dc-link capacitance and the multiphysics design of the bus-bar. The parasitics of the bus-bar part of the proposed dc-link structure are evaluated using electromagnetic finite element method (FEM) models and their influence on the dc-link waveforms is evaluated. Due to the expected high ambient temperature inside an integrated drive, electromagnetic and computational fluid dynamics (CFD) models are developed for the proposed dc-link structure to evaluate the loss density and the temperature distribution of the bus-bar to ensure reliable operation. An experimental setup is built to validate the design methodology.
