Abstract
For use with a power supply including first and second parallel-coupled converters having interleaved first and second switches, respectively, the first and second switches limited to a duty cycle of less than about 50 percent, a current mode control circuit and a method of current-mode controlling the power supply. In one embodiment, the current mode control circuit, includes: (1) an interconverter current transformer, coupled to an input of the power supply, that senses an input current of the power supply and (2) a controller, coupled to the current transformer, that moderates the duty cycle of the first and second switches as a function of the input current to cause the first and second converters to share an output current of the power supply.
