Design of 1kW inductive power transfer system for electric vehicle

A brief review: basic coil designs for inductive power transfer

“…R. A. Deshmukh and D. B. Talange [15] proposed the IPT system that is capable of transferring 1 kW power over 10 cm air-gap at 15 kHz frequency with 95% efficiency. R. Vaka and R. Kumar [16] suggested an extended idea of asymmetrical CSC as the geometry design of the coupler coils.…”

Talange [15] discussed the procedures in designing a 1 kW power for the IPT system. The authors analyzed the magnetic parameters of the DWC inductive coupling coils which implement the circular spiral coil geometry at both sides, transmitter and receiver coils.…”

“…Therefore, since the load and WPT coil inductances are the factors affecting the power transfer, this will cause the transmitter coil to have a high VA rating and thus, reducing the efficiency of the overall system. However, R. Deshmukh and D. Talange [15] found that capacitive compensation in both transmitter and receiver coils is much recommended to magnify the operating frequency while improving the power factor by employing the CSC geometry. The CSC is well-known because of its excellent magnetic properties and electrical properties which results in its simplicity to experiment on [63].…”

“…However, only the inductive coupling principle has extensively applied to not only EV but also to supply power to household appliances, biological implants and other means of transportation such as buses and shuttle vehicles [11][12][13][14]. Currently, most researchers are focusing on the PTE, coil geometry, coupling coefficient, misalignment tolerant and air-gap between the coupling coil [15][16][17]. The focus of this paper is to briefly discuss the basic coil geometry designs of the IPT system for EV, which applied either to the static charging or dynamic charging.…”

Kablosuz Güç Aktarımı için Karşılıklı Endüktans Hesaplama Aracının Geliştirilmesi

“…Bu değişkenlerin karşılıklı endüktans üzerindeki etkisinin analizi ve kablosuz enerji aktarım sistemlerinin verimin artırılmasına yönelik literatürde birçok çalışma bulunmaktadır. Bu çalışmalarda genellikle kapsamlı paket programlar kullanılarak modelleme yapılmakta ve karşılıklı endüktans değeri elde edilmektedir [17][18][19][20][21][22][23][24].…”
