A method of controlling a voltage regulator (10) having a nominal input and a nominal output structured to operate in a forward power mode wherein power flows from the input to the output and a reverse power mode wherein power flows from the output to the input. The method includes sensing current flowing through the voltage regulator (10), determining a direction of power flow through the voltage regulator (10) based on the sensed current, determining a verified direction of power flow through the voltage regulator (10) by altering a voltage between the input and the output and analyzing an effect caused thereby on at least one of a voltage at the input and a voltage at the output, and selecting a voltage regulating scheme for controlling the voltage regulator (10) based on the verified direction of power flow. |
