摘要
以最大的效率减少设备和系统的体积，导致高成本，使优化设计成为工程师的巨大挑战。在功率因数校正(pfc)变换器中，作为电感和变压器的磁性元件对系统的成本、体积、功率密度和性能有着重要的影响，成为其重要组成部分。因此，对这些组件进行优化设计的需求是极其重要的。为此，本文提出了一种1kW, v220vac, VOUT 400VDC, PFC升压变换器的电感设计。该设计采用不同的工作点(Δi @ fs)和不同的磁性材料技术(Molipermalloy, High Flux和KoolMμ)进行比较分析。这些粉末材料对全氟碳化物具有极具吸引力的特性，本文指出了上述三种磁性材料技术中哪种材料具有最佳的成本/效益关系。
A comparative design of an optmized boost inductor taking into account three magnetic materials technologies: Volume, cost and efficiency analysis
Reducing the volume with maximum efficiency, on equipment and systems, result in a high cost, making the optimized design a great challenge for engineers. On power factor correctors (PFCs) converters, magnetic elements as inductors and transformers have a strong influence on cost, volume, power density and performance, they become the more important elements in these systems. Thus, the need for an optimized design of these components is extremely important. With this purpose, this paper presents the inductor design for a 1kW, VIN 220VAC e VOUT 400VDC, PFC boost converter. The design is developed using different operating points (Δi @ fs) and different magnetic materials technologies (Molipermalloy, High Flux and KoolMμ) to perform a comparative analysis. These powder materials have extremely attractive characteristics for PFCs and this paper indicates which material offers the best cost / benefit relationship between the three technologies of magnetic materials aforementioned.
