In this paper, the compensator for the CCM voltage-mode tapped-inductor buck converter is selected and designed. The type 3 compensator, which provides a 90o phase boost, is selected for the CCM voltage-mode tapped-inductor buck converter. By designing the double zero, double pole, and crossover pole, the type 3 compensator can be obtained. Finally, the effectiveness of the closed-loop load transient response of the tapped-inductor buck converter is verified by the PSIM.
