Contents I. Introduction
DC-DC converters are widely utilized in the automotive, aerospace, and power grid industries, among others. High-power-density magnetic designs are in high demand in all these industries. The key to reducing the weight and volume of power converters lies in a compact and efficient magnetic design [1]. The size of the inductor is impacted by several design considerations, such as the number of stages and the choice between continuous and discontinuous conduction modes [2]. The selection of appropriate dimensional ratios for the core can significantly reduce the size of the inductor [3], and additional size reduction can be achieved through the implementation of improved cooling methods [4]. Typical switching frequencies of DC-DC converters lie in the range of 1 kHz to 1 MHz, depending on the semiconductive devices used [15]. Therefore, high frequency magnetic design is required. The designer has access to a range of magnetic materials for high frequency applications, such as powder, ferrite, and tape wound cores [5]. The correct choice of magnetic material is imperative to ensure a cost-effective inductor with minimum size and maximum efficiency for the specific converter to be designed.
