Resonant power conversion is an effective technology for various applications. This paper presents a resonant magnetizing approach, aimed at improving the low power density and cost issues of traditional capacitor-discharged impulse magnetizer. In the method, a resonant tank is established by a series capacitor and inductor. Then, by periodically switching power transistors inside the circuit, the...
This paper proposes a dc power supply system to give high power factor and low current distortion on the rectifier side and provide stable dc voltage on the isolated dc/dc converter side. The proposed dc power supply system uses a new ZCS strategy to get ZCS function. Besides operating at constant frequency, all semiconductor devices operate at ZCS without additional current stress. A significant...
This paper describes lateral misalignment characteristics of electrical resonance coupling wireless power transfer (ERC-WPT) from experimental points of view. A dead zone is an important factor for ERC-WPT because ERC-WPT cannot transfer electric power in the zone. Electrical coupling units that are composed of 2 electrodes lined up laterally have a dead zone. The dead zone exists near outer edge...
Wireless Power transfer using electric field can realize highly efficient electrical power transmission and the transmission units are thin and light. However, the transmission system produces large electric field intensity and the electric field noise can make other electronic devices malfunction. A shield box is greatly effective to reduce the electric intensity 60dB without a decline of transmission...
This paper proposes a current-fed two inductor bi-directional DC-DC converter using resonance (CF-TIBCR). The power losses of CF-TIBCR mainly occur in switches, especially the low voltage side switches. To improve the efficiency, the detailed loss analysis of switch and magnetic components is performed from the steady state analysis and operation principles. To verify theoretical loss analysis, it...
