Abstract
A method and an apparatus are provided for balancing current for each of a plurality of similar phases of a DC/DC boost converter. The method includes the step of measuring a voltage drop of each of the plurality of similar phases at predetermined times by measuring the voltage drop across each phase switching device when current is flowing through the switch. The method also includes the steps of calculating current information for each of the plurality of similar phases in response to the voltage drop measured for each of the plurality of similar phases and balancing current for each of the plurality of similar phases in response to the current information of each of the plurality of similar phases.
