Abstract
A method and system are provided for updating a duty cycle for a power converter. The system and method operate the power converter to compute a first duty cycle during a first pulse-width modulation period and updating a second duty cycle for a second pulse-width modulation period at the completion of the first pulse-width modulation period. Next a third duty cycle for a third previous pulse-width modulation period is updated at the completion of the first pulse-width modulation period.
