چکیده
This paper presents the modeling, design and verification of a three-phase coil structure for high-power Wireless-Power-Transfer (WPT) in automotive applications. The system, Three-Polar-Pad (TPP), with complex mechanical geometry, is analytically modeled an equivalent simplified structure. Thanks to this simplification, numerical performed minimize cross-coupling effects among different phases same side (receiver or transmitter) maximizing linkage flux receiver-to-transmitter then power transferred. analytical model verified Finite-Element-Analysis (FEA) environment. A final design, comprehensive shielding, proposed matching preliminary constraints. Hence, by testing prototype using Silicon Carbide (SiC) inverter at transmitter side. capability system demonstrated transferring 100 kW more than 94% DC-to-DC efficiency over 50 mm air gap perfectly aligned conditions.

15 صفحه اولDesign and Control of a 3 kW Wireless Power Transfer System for Electric Vehicles
This paper aims to study a 3 kW wireless power transfer system for electric vehicles. First, the LCL-LCL topology and LC-LC series topology are analyzed, and their transfer efficiencies under the same transfer power are compared. The LC-LC series topology is validated to be more efficient than the LCL-LCL topology and thus is more suitable for the system design. Then a novel q-Zsource-based onl...
متن کاملDevelopment of a 60 kHz, 180 kW, Over 85% Efficiency Inductive Power Transfer System for a Tram
Conventional contact-based train power transfer systems have high maintenance costs and safety issues and cause noise and additional aerodynamic drag. Instead of the conventional system, a loosely coupled online wireless power transfer (WPT) system for a train is proposed in this paper. The operating frequency of the proposed design is 60 kHz to ensure a low flux density and a high-efficiency s...
متن کاملLong range inductive power transfer system
We report upon a recently developed long range inductive power transfer system (IPT) designed to power remote sensors with mW level power consumption at distances up to 7 m. In this paper an inductive link is established between a large planar (1 x 1 m) transmit coil (Tx) and a small planer (170 x 170 mm) receiver coil (Rx), demonstrating the viability of highly asymmetrical coil configurations...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
