efficiency, and transferable power. In a typical application as electric vehicle charging, the secondary side coil is attached on the bottom side of the vehicle. The primary coil side is put on the ground. This assembly is ensured to have flux in between those two coils by using ferrite...
Furthermore, ME-based power transfer also demonstrates encouraging angular misalignment tolerances. In comparison with inductive coils that harvest power on the basis of magnetic flux, the ME materials harvest power on the basis of magnetic field strength. As a result, it has been shown that ME ...
This paper describes the control of a wireless power transfer system using a double DD coil structure, when the transmitter and the receiver coil are rotated to one another. WPT systems using single DD coils are rotationally dependent, due to the directional magnetic field ...
Polarized DD CoilsSelf-inductanceWireless Power TransferSelf- and mutual inductances are major design parameters for wireless power transfer (WPT) systems. To optimize a WPT system and estimate its performance in terms of received power and efficiency, it is essential to obtain a simple, fast, ...
First, the structural characteristics of the DD spiral coil are introduced, and the mutual inductance relationship between the coils is obtained; then the output characteristics of the single-input-double-output LCC-LCC compensation system are analyzed. Without using complex control methods, the system...
Wireless power transferElectric vehiclesThis paper proposes a dynamic wireless power transfer system with parallel transmitters for electric vehicles. The transmitter consists of two DD type coils which connect with one inverter in parallel. To overcome the power-null phenomenon, one additional rectangular...
The distance between the two unipolar coils of the extended DD coil is optimized to maximize the magnetic flux on the secondary transfer path, thereby increasing the total power of the system misaligned state. Simultaneously, the most suitable turns and inner diameter of the exten...
A wire bond free power module assembly consists of a plurality of individual thin packages each consisting of two DBC wafers which sandwich one or more semiconductor die. The die electrodes and terminals extend through one insulation covered end of the wafer sandwich and the outer sides of the ...
