A novel cubic transmitter for multi-directional wireless power transfer

An effectively designed multi-directional wireless charging system is a highly attractive and economic strategy for simultaneously charging a multiple of devices. An open-ended coupling system with a novel cubic transmitter is presented to arise in receiver applications and achieve a relative high efficiency. The cubic transmitter is driven by a single power source with the same ac current. The energy delivery is transmitted to the receivers through the magnetic resonant coupling in the medium range wireless power transfer mode. The efficiency of the proposed multi-directional wireless power transfer system is almost higher than 50%.
