Abstract :
A thorough and systematic evaluation of different digital control design approaches is presented. The performance of the approaches is compared in terms of both the bandwidth and the phase margin of the control loop, as well as the output transient response subject to line and load step change. Furthermore, the difference of these design approaches under a lower sampling rate is studied. Best digital design approach for power converter applications is identified based on the comparison results
