Abstract:
A single stage DAB control circuit for converting an unbalanced grid voltage into a DC voltage is provided. The control circuit includes a controller having a voltage detection module, a first transformation module, a level shift module, and a second transformation module. The voltage detection module provides voltage component values that are indicative of the voltage in each phase of a three-phase AC power supply. The first transformation module converts the voltage component values from a stationary reference frame into reference voltage signals in a rotating reference frame using a Clarke-Park transform. The level shift module compensates the reference voltage signals to simulate an ideal or balanced three-phase AC voltage. The second transformation module converts the compensated reference voltage signals from the rotating reference frame to the stationary reference frame using an inverse Clarke-Park transform. The controller is then operable to control operation of a single stage DAB converter for providing a DC charging voltage to a battery that is substantially free of fluctuations or ripple.

Claim (Index 17):
A controller for controlling a single stage converter for charging a vehicle battery, the single stage converter including a first phase DAB, a second phase DAB, and a third phase DAB, the controller comprising:\n a voltage detection module adapted to provide voltage component values indicative of the value of the voltage in each phase of a three-phase AC power supply; a first transformation module and adapted to convert the voltage component values into first and second reference voltage signals in a rotating reference frame; a level shift module adapted to compensate the first and second reference voltage signals to simulate a balanced three-phase AC power supply; a second transformation module adapted to convert the compensated first and second reference voltage signals from the rotating reference frame to a stationary reference frame, the second transformation module providing, as an output, a first power reference, a second power reference, and a third power reference; and a converter control module adapted to control operation of the first phase DAB, the second phase DAB, and the third phase DAB based on the output of the second transformation module for providing a DC charging voltage to the vehicle battery.
