Analysis and design of type 3 compensator for the boost converter based on PSIM

In this paper, the compensator for the CCM voltage-mode boost converter is selected and designed. First, by using Mathcad, the type 1, type 2, and type 3 compensators are analyzed and developed from the basics. From the compensator analysis, one can know why the type 3 compensator is suitable for the CCM voltage-mode boost converter. Second, by selecting the type 3 compensator, which provides the required phase margin boost, the parameters of the type 3 compensator can be obtained. Finally, the effectiveness of the closed-loop load transient response of the boost converter is verified by Mathcad and PSIM.
