“…Table I details the set of electromagnetic FE analyses, along with the appropriate winding current, frequency and temperate cases, required to characterise the electromagnetic and loss behaviour over the temperature range of interest at a fixed frequency, f 0 , Sections II-A1 to II-A3. The electromagnetic model assumes pure sinusoidal excitation current, however, non-sinusoidal current can be approximated by decomposing the waveform into its Fourier components and evaluating the FE model at each significant harmonic along with the dc average and superimposing the result, [20], [25]. Hence, the number of FE analyses required, N EM , to characterise the electromagnetic and loss behaviour is given by, (6), where N h is the number of significant harmonics.…”

Abstract-Cloud computing is a type of distributed computing that enables public, on-demand network (internet) access to a large pool of shared computing resources, making it easier than ever to outsource computing tasks on a pay-as-you-go basis. In this paper, a cloud computing service is used to complement an existing high-fidelity multi-physics power inductor design workflow by enabling multiple instances of the design analysis to be executed in parallel on virtual computers in a cloud computing environment. This method accelerates the design development cycle and can allow a more thorough evaluation of the design space within a short time-frame, at a moderate cost and can potentially lead to improved designs. The modified workflow is demonstrated by the design optimisation of a high-energy-density filter inductor for an automotive application.

“…Using the automotive converter, it is illustrated how the design interactions between the electrical, thermal and mechanical designs can be manipulated to produce a final converter structure meeting the operating temperature and volume requirements. The complete design and analysis of the two case studies are not repeated in these sections and can be found in [9]- [12].…”

“…For example, improving the thermal management of the inductors implemented in the automotive converter can be achieved by integrating the inductors into special heatsink structures called integrated heatsinks [9], [10], [12]. These structures are used to place the inductors in the third dimension above the bus capacitors or switching devices, as well as to remove the heat from the component with a small .…”

“…The inductor windings are clamped so that the current density can be significantly increased without a large increase in the temperature drop between the inductor and thermal interface. There are two heatpaths connecting the inductor structure to the thermal interface to transport the heat dissipated in the component to the thermal interface [9], [10].…”

Abstract-Power electronics is finding increasingly more applications in high temperature environments where power density is also a driving factor. The engine compartment of a passenger vehicle is one such example. In this paper, an integral thermal, electrical, and mechanical design of a high power density dc/dc converter operating in the thermally harsh automotive environment is discussed. The interactions and interdependencies between the three design disciplines are considered. It is illustrated how these interactions can be manipulated and used to an advantage in meeting the harsh temperature and high power density requirements of the automotive converter. Packaging and circuit techniques are identified that can be used to this end.Two case studies of a 2-kW 14-V/42-V dc/dc converter for application in the automotive environment are considered. The first prototype achieved a power density of 170 W/in 3 while the second prototype, operating with a higher environmental temperature achieved a power density of 120 W/in 3 . The experimental structures and practical results are presented. Technology issues concerning the three-dimensional construction of the prototypes that need research attention are also identified.Index Terms-High power density dc/dc converter, three-dimensional (3-D).
