The Digital Compensator Design Tool (DCDT) helps power supply designers by simplifying the overall process of determining the digital compensator coefficients and analyzing the control system performance. The DCDT incorporates all feedback gains and delays to provide the most accurate model of the control system. Along with analyzing the closed-loop performance via Bode plots, the user can verify stability by using the DCDT’s root locus and Nyquist plots. Once the desired performance is obtained, the DCDT will automatically calculate the compensator coefficients and scaling parameters and generate software files to be used with the free Switch Mode Power Supply (SMPS) Control Software Libraries.
