The wireless charging system based on magnetic resonance technology is real “unmanned”. No need to plug in, no contact, no need to be accurate, the robot can charging. It will not cause the charging failure caused by poor electrode contact. No naked electrode, no fear of thunderstorms, no electrode oxidation and dirt loss, no arcs and fires affecting life and property. <br> <br>What is the principle of magnetic resonance wireless charging? In fact, it is the establishment of wireless communication between the user’s equipment and the transmitting end. In the transmitting end, each module will convert single -phase frequency 220V AC power through rectification and inverter to high -frequency AC current supply launch coil. The resonance between the transmitting coil and the receiving coil is transmitted from the transmitting coil to the receiving coil from the launch coil to the receiving coil, so as to ensure that the power energy can be effectively transmitted to the power consumption equipment and realize the power supply equipment.
