摘要： A high-efficiency electrical energy transmitting end and a wireless electrical energy transmission device are provided. A soft-switching control circuit controls the voltage waveform between two ends of a switching device of an inverter circuit. During disconnection of the switching device, a voltage waveform between the drain electrode and the source electrode is a waveform in the form of a fundamental wave superimposed with a third harmonic, enabling the switching device to be turned on at zero voltage to decrease the switching loss. Through a current regulation circuit, the primary transmitting current is controlled to have constant frequency and constant amplitude to ensure that the primary transmitting energy won't be affected by the changes of the coupling and load and to enhance the transmission efficiency. The transmission efficiency of the wireless electrical energy transmission device of the present invention is high and the reliability is better.

摘要： A contactless power transmission device and a power transmission method are disclosed herein. When a rectifier filter circuit receives high-frequency AC output from receiving coil and after a full-bridge rectifying and filtering process, DC voltage signal is obtained. When the DC voltage after rectifying and filtering is detected to exceed the preset value, a current loop is formed using a switch protection circuit, an impedance matching circuit and a receiving coil, to transfer the energy of receiving coil until the voltage drop to no higher than the preset value. Of which, the switch protection circuit is connected between the impedance matching network and ground, when the power transmission device is in normal working, the switch protection circuit does not work; when an overvoltage occurs, the switch protection circuit can switch on/off, to reduce the value of DC voltage.

摘要： An electrical energy receiving end capable of overvoltage protection and a wireless electrical energy transmission device are provided. An electrical energy receiving coil is divided into a first receiving coil and a second receiving coil, so that under normal operation the first receiving coil and the second receiving coil jointly resonate with an impedance matching network to receive energy. When the electrical energy receiving end has an overvoltage, the first receiving coil and the impedance matching network (or the second receiving coil and the impedance matching network) form a loop, and due to the impedance mismatch, the energy received by the electrical energy receiving end is greatly reduced to solve the problem of overvoltage at the electrical energy receiving end.

摘要： An electromagnetic shielding layer and a wireless electrical energy transmission device having the electromagnetic shielding layer are provided. A first shielding layer is composed of a hollow area and a solid area. At the hollow area, because the magnetoresistance of the air is greater than the magnetoresistance of the magnetic sheet, it is not easy for the magnetic lines of flux of the high frequency magnetic field of the primary transmitting coil to pass the hollow area, so that the inductance value of the primary transmitting coil won't be affected easily by the change of the magnetoresistance during working Under the receiving coil is provided with magnetic sheet as much as possible to ensure the coupling of the receiving coil and the transmitting coil and to enhance the transmission efficiency.
