摘要:
A direct current-to-direct current (‘DC-DC’) converter generates a pulse-width modulated (‘PWM’) control signal, and generates an output voltage from an input voltage as a function of a duty cycle of the PWM control signal. A feed-forward module controls both the duty cycle and a repetition rate of the PWM control signal as regressive functions of the input voltage so as to tend to compensate for variation in the input voltage.
