The transfer function of the duty cycle to the output voltage of the Boost controller in the inductor current continuous conduction mode ( CCM) mode is analyzed. Due to the existence of the second-order oscillation link and the zero point of the right half plane, if the single-pole compensation network is used under the single-voltage control, the crossing frequency of the corrected system is less than the natural oscillation frequency, and it is difficult to have good dynamic performance. In order to improve the control bandwidth of the system, a controller is composed of a double pole double zero point compensation network and a phase lead compensation network to compensate the Boost single voltage. In this paper, the parameters of the controller are calculated in detail, and the correctness of the controller design is verified by simulation. Compared with the single pole controller, it shows that the controller has good rapidity and stability.
