Claim 0:
1. A boost converter control system comprising:
a phase compensator to receive a first duty cycle measurement of a first converter of an interleaved boost converter and a second duty cycle measurement of a second converter of the interleaved boost converter, to compare the first duty cycle measurement to the second duty cycle measurement and to generate a phase compensation in response to the comparison;
a phase combiner to combine a phase adjustment output and the phase compensation to produce a phase control output; and
a cycle controller coupled to the first and the second converters to generate a first drive signal to control switching of the first converter and to generate a second drive signal to control switching of the second converter,
wherein a time of the second drive signal is adjusted using the phase control output; and
wherein the comparison comprises a ratio of a difference between the first duty cycle measurement and the second duty cycle measurement and a sum of the first duty cycle measurement and the second duty cycle measurement.
