Multi-phase Interleaved AC to DC Buck-boost Converter with Active Power Decoupling Function and Sliding-mode Control Strategy

摘要

This paper proposes an interleaved AC/DC buck-boost converter with active power decoupling(APD) using the modular design method. It also introduces the control method using the sliding mode control (SMC) strategy for the proposed circuit. The contribution of this paper was first proposed by AC/DC Interleaved Converter circuits with APD functions, which allowed the size of input filters and magnetic cores to be reduced. Additionally, we have applied SMC strategies to the control system to be robust for the disturbance or model uncertainty. The effectiveness of the proposed circuit and control method is shown by simulations using MATLAB/SIMULINK.
