“…ATU mass is determined using a power density ratio of 6.39 kVA/kg [29] and filter and diode component masses are determined from manufacturer datasheets. It is assumed [10] that the ATRU is liquid cooled and mass of the cooling plate and pipes is derived using the method outlined in [11]. The total mass of the 250kW and 130kW rated devices are provided in Table 1.…”

Mass and efficiency are key performance indicators for the development and design of future electric power systems (EPS) for more-electric aircraft (MEA). However, to enable consideration of high-level EPS architecture design trades, there is a requirement for modelling and simulation based analysis to support this activity. The predominant focus to date has been towards the more detailed aspects of analysis, however there is also a significant requirement to be able to perform rapid high-level trades of candidate architectures and technologies.Such a capability facilitates a better appreciation of the conflicting desires to maximize availability and efficiency in candidate MEA architectures, whilst minimizing the overall system mass. It also provides a highly valuable and quantitative assessment of the systemic impact of new enabling technologies being considered for MEA applications. Without this capability, predesign assessments are often time consuming and of a qualitative manner. Accordingly, this paper will present a steady state pre-design analysis tool for MEA architectures, which enables analysis of the architecture performance at different stages of the flight profile. By providing drag and drop models of key MEA electrical power system components configured for common voltage and power levels, the tool facilitates the rapid construction of candidate architectures which then enables the subsequent quantitative assessment of overall system mass and efficiency. Key to the credibility and usefulness of this tool, is the appropriate marrying of validated fundamental mathematical models (for example in the evaluation of system losses), up-to-date data driven models (for example, relating to component masses or power densities) and the flexibility to incorporate new models of technologies under consideration. The paper will describe these core elements and present selected case studies demonstrating potential uses of the tool in architecture assessment and down-selection, technology impact, and design-point sensitivity analysis.

“…Therefore, a passive filter is needed at the grid side of the HPDC to ensure good power quality [2][3][4][5] and LCL filters are commonly adopted for this purpose [6][7][8]. In a LCL filter, inductors usually account for nearly half the total weight of the entire HPDC and hence, their designs are crucial if weight is a major design consideration [9]. Conventionally, three-phase inductors are wound on rectangular composite core [10].…”

The magnetic component is considered one of the major factors that dominate the power density of power converters. In this paper, magnetic integration of inductors of a three-phase LCL filter on delta yoke composite core is explored and investigated. Using the conventional rectangular core as the baseline design reference, the proposed delta yoke core achieved a weight reduction of close to 10% without affecting the filter's performance. The inductances based on both shapes were calculated and verified through magnetic circuit analysis and 3-D finite element analysis (FEA) simulation. Hardware prototypes of the integrated inductor with both the conventional rectangular and the proposed delta yoke cores were fabricated and tested with a three-phase inverter circuit to verify the design validity.Index Terms --Delta yoke core; Magnetic integration; LCL filter; High power density converter I.Rejeki Simanjorang (SM'16) was born in Tanah Karo, Indonesia.

Abstract-The fast switching speeds and low specific conduction losses of wide band-gap semiconductors allow the realisation of high-frequency, high power-density switching converters with dramatically reduced passive component requirements compared to Silicon technology. However, careful attention must be paid to switching cell design to mitigate the effects of circuit parasitics and fast voltage transitions which would otherwise limit the attainable switching speed and lead to increased levels of EMI. This paper presents a modular, powercell solution which allows the creation of any two-level topology converter. The cell structure enables fast switching of wide bandgap semiconductor devices while allowing high power converters to be fabricated using multiple, smaller commutation cells. Close integration of semiconductor dies, decoupling capacitors, gate drives and an output filter with a single ceramic substrate to act as the thermal path allows dramatic increases in power density without compromising converter performance.
