Patent ID: 8228014

Claim:
A direct current-to-direct current (DC/DC) boost converter comprising: a plurality of similar phases for boosting a DC voltage provided at an input to the DC/DC boost converter, each of the plurality of similar phases having a current associated therewith and each of the plurality of similar phases including a corresponding one of a plurality of voltage drop measuring devices; and a boost converter controller coupled to the plurality of voltage drop measuring devices for generating and providing gate drive signals thereto and for measuring a voltage drop of each of the plurality of similar phases at predetermined times across each of the corresponding ones of the plurality of voltage drop measuring devices, the boost converter controller calculating current information for each of the plurality of similar phases in response to the voltage drop of each of the plurality of similar phases, wherein the boost converter controller balances current for each of the plurality of similar phases in response to the current information of each of the plurality of similar phases, wherein each of the plurality of similar phases comprises a temperature sensing device for measuring a temperature thereof, and wherein the boost converter controller is coupled to the temperature sensing device of each of the plurality of similar phases and calculates the current information of each phase of the plurality of similar phases in response to the measured temperature and the measured voltage drop thereof.
