Abstract: A power transfer system and method are provided for transferring power from an AC supply outputting a first AC voltage. The system includes a controller and a matrix converter coupled to the AC supply for converting the first AC voltage to a second AC voltage. A primary coil is connected to the matrix converter and a secondary coil is in communication with the primary coil for producing an induced AC voltage. A secondary rectifier is connected to the secondary coil for rectifying the induced AC voltage to produce a secondary DC voltage. A sensor is coupled to the secondary rectifier and to the controller for monitoring the secondary DC voltage and outputting a proportional signal. The controller is configured to control the matrix converter producing a desired second AC voltage at a desired operating frequency and maintain a predetermined secondary DC voltage in response to the signal from the sensor.

Abstract: A power transfer system and method are provided for transferring power from an AC supply outputting an AC voltage. The system includes a controller and a primary rectifier coupled to the controller and to the AC supply for converting the AC voltage to a DC bus voltage. An inverter is coupled with the primary rectifier and the controller for converting the DC bus voltage to a primary AC voltage. A primary coil is connected to the inverter. A secondary coil is in communication with the primary coil for producing an induced AC voltage. A secondary rectifier is connected to the secondary coil for rectifying the induced AC voltage to a secondary DC voltage. At least one sensor is connected to the secondary rectifier for outputting a signal proportional to the secondary DC voltage and the controller is configured to vary the DC bus voltage based on the signal from the sensor.
