This paper introduces a concept design for a high-frequency power transmitter with application in electrical machines for automotive industry. In the first part of the paper, modeling and optimization of contactless transmitter is discussed. In this second part of the paper, focus is placed on the selection of suitable materials for the transmitter core. Characteristics of different material alternatives including Ferrites, thin non-oriented steel lamination and Soft Magnetic Composites are presented. The performance and the efficiency of the transmitter with above mentioned material candidates are elaborated and discussed. It is shown that Ferrites, despite its low saturation level, are the most suitable material for this application where the power is relatively low and a high-level operation frequency is required.

Abstract
This paper introduces a concept design for a high-frequency power transmitter with application in electrical machines for automotive industry. In the first part of the paper, modeling and optimization of contactless transmitter is discussed. In this second part of the paper, focus is placed on the selection of suitable materials for the transmitter core. Characteristics of different material alternatives including Ferrites, thin non-oriented steel lamination and Soft Magnetic Composites are presented. The performance and the efficiency of the transmitter with above mentioned material candidates are elaborated and discussed. It is shown that Ferrites, despite its low saturation level, are the most suitable material for this application where the power is relatively low and a high-level operation frequency is required.
