Abstract A phasor control method is employed in this paper to eliminate the circulating current caused by the parallel connected high frequency inverters.The topology of the parallel dual-inverter LCCL-based inductive power transfer (IPT) system and the cause of circulating current are analyzed in detail.Secondly, the virtual active/reactive power based on the current of the primary coil are calculated without using the phase-locked loop, the relationship between the goal of the phasor control and the virtual active/reactive power is analyzed, and then the circulating current eliminating approach is provided.The performance of the proposed approach is evaluated by the experimentation of two parallel connected high frequency inverters with 1.4 kW maximum transmission power and overall 89.82% DC-DC transmission efficiency.The experimental results demonstrate that the circulating current between the parallel connected inverters is dramatically reduced by the proposed algorithm.

Key words： Parallel high-frequency inverters technology inductive power transfer phasor control circulating current eliminating virtual active/reactive power
