Grid voltage emulation at the secondary side of a contactless power supply

Conventional contactless power supply systems deliver in most of the cases a DC-voltage or a DC-current at their output. In case of a need for an AC-grid voltage on the secondary part to feed common grid frequency loads, an inverter may be connected to the DC-output of the contactless system to generate an AC-voltage emulating the voltage of the grid. However this solution requires high number of components and has low system efficiency. A new rectifier topology for inductive power systems able to emulate the grid voltage is presented and compared with the conventional inverter solution and a matrix inverter based solution.
