Abstract
- In this paper, the effects of the resonant network characteristic and control variables on the dc-link capacitor of a wireless charger are investigated for electric vehicles, by deriving an analytical expression for the capacitance in terms of the resonant network parameters and system control variables. With this equation, the minimum dc-link capacitance needed can be obtained to keep the dc-link voltage ripple within a desired limit for a wide load range. A comparison between the conventional series-primary resonant networks in terms of the dc-link capacitance needs is presented as well as simulation results to validate the derived equation.
