摘要：A pulse width modulator (PWM) control system for a power converter achieves

a fast transient response and low steady-state jittering. The control system manages theADC sample timing to reduce noise susceptibility, and the ADC includes a regulation binor dead band to minimize large phase corrections and thus eliminate limit cycling. ThePWM module includes a dithering circuit to accumulate fractional PWM control signals toreduce period jitter by increasing the effective resolution of the pulse width modulator.
