The present disclosure relates to a capacitive power transfer system comprising: a DC power source providing an input DC supply voltage; an inverter configured to convert the DC supply voltage into an AC power; a capacitive coupler configured to transfer the AC power wirelessly; an LCL compensation topology arranged between the inverter and the capacitive coupler; a rectifier configured to convert the wirelessly transferred AC power into a DC output, said DC output connectable to a load; and a control unit configured to control the DC power source and/or the inverter such that the capacitive power transfer system: in a constant current mode, operates at a constant current mode frequency (fcc), wherein a constant current is provided to the load; and in a constant voltage mode, operates at a constant voltage mode frequency (fcv), wherein a constant voltage is provided to the load. The present disclosure further relates to a method for controlling the capacitive power transfer system.
