Dynamic WPT systems are extensively investigated as a promising solution to the issues of the comparatively short range and long recharge time of the electric vehicles. In dynamic WPT systems, the lumped tracks exhibit greater power transfer efficiency than the stretched ones but require the supply of a large number of transmitting coils. This paper proposes a command strategy for a dual-output inverter that allows the concurrent supply of two track coils, with the ability of adjusting independently the voltage applied to each of them without altering the phase relation between the two supply currents. Moreover, if the series resonant compensation is used at the track side, the proposed strategy is robust against the onset of a reactive component in the loads seen at the inverter outputs as it inherently corrects the phase of the coil currents without making recourse to any additional control algorithm.
