Description

technical field [0001] The invention relates to a wireless power transmission device, in particular to a resonant wireless power transmission device. Background technique [0002] Currently, wireless power transmission devices mainly include three types: the first type is a wireless power transmission device based on electromagnetic coupling. This kind of device uses the principle of mutual coupling of common magnetic coils for wireless energy transmission. Its advantage is high transmission efficiency, but its problem is that the transmission distance is short (centimeter level). The second is a wireless power transfer device based on radio waves. This kind of device uses the principle of far-field antenna to transmit and receive wireless energy. Its advantage is that the transmission distance is long (kilometer level), but its problem is that the transmission efficiency is low. The third is a wireless power transmission device based on electromagnetic resonance. This de...
