This paper presents duty control and analysis of the three-phase voltage source inverter (VSI) to adjust the output power for three-phase wireless power transfer (WPT) applications. Analytical results show significant reductions in the inverter dc link ripple current with the three-phase system over single-phase WPT counterparts. Simulation and experimental results for an 18 kW three-phase series-series WPT system are included to validate the duty control and analysis. Experimental results also demonstrated the output voltage can be controlled over a wide range by adjusting the inverter duty.
