Abstract：Aimed at the power transmission control for three-phase wireless power transfer system, three-phase wireless power transfer system adopted the series resonant inverter in primary side is analyzed detailedly. Aimed at the difficulty on power control caused by three-phase unbalanced current under unbalanced load, based on that the PR controller can realize the tracking control of sinusoidal signal for a certain frequency, balancing control is conducted for primary three-phase current by adopting PR controller in αβ coordinate system. The results of simulation and experiment indicate that PR controller can realize the tracking control of the load current of three-phase series resonant inverter which can solve the unbalance of three-phase and provide the basis for the power control of three-phase wireless power transfer system.
