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 14):
The method of  claim 11  wherein converting the voltage component values from a stationary reference frame in the rotating reference frame includes performing a three-phase Phase Lock Loop (PLL) algorithm.
