This paper put forwards a novel contactless energy bi-directional transfer mode to realize energy exchange between transmitter and receiver. The paper presents a bi-directional energy conversion topology and set up its equivalent circuit and piece-wise state space model. The simulation results show that system resonant state have low harmonic components. It’s benefit to improve system efficiency and minimize EMI interference. The bi-directional energy transfer mode can be used in energy exchange between mobile devices and energy feedback from mobile device to power grid to improve system efficiency.
