摘要
Provided are a resonant coil array-based wireless electric energy transmission system and a control method therefor. The system comprises a transmitter (100) and multiple receiving end loads (200). Multiple resonant units (20) of the transmitter are arranged in an array, and correspondingly arranged are multiple row wires (30) and column wires (40) that are of numbers corresponding respectively to the number of rows and the number of columns of the array. Also, each row wire is connected simultaneously to multiple resonant units of a same row in the array, and each column wire is connected simultaneously to multiple resonant units of a same column in the array, while the other ends of the row wires and of the column wires respectively are connected to corresponding pins of a transmitter MCU (10). The resonant units comprise a resonant coil (21) and a time delay switch (22). A changing magnetic field is generated at the transmitter by controlling the closing or opening of the delay switches, and the multiple receiving end loads pickup energy from the changing magnetic field. The system and the control method therefor reduce the number of components and prevent energy surge loss due to frequent scanning and gating.
