Abstract

This paper discusses current control techniques for utility interface converters with low total harmonic distortion (THD), fast dynamic responses, and high stability for transient responses. A repetitive control technique with designed phase margin has been developed to reduce the THD of a single-phase boost AC/DC converter operating over a wide range of load variations. A green-mode control strategy is developed to adjust the control mode as well as the switching frequency for efficiency improvement. A predictive current loop controller is used to achieve fast dynamic response under wide input voltage variation range and a repetitive controller is designed to minimize periodic errors within the current loop bandwidth. A single-chip DSF controller is used to realize the proposed control scheme. Simulation and experimental results confirm the feasibility and performances of the proposed control scheme.
