Review on Control Strategy for Improving The Interleaved Converter Performances

An interleaved converter provides several advantages over non-interleaved converters. Therefore, many researchers have proposed control methods to improve its performance. Control strategy generating variable-frequency (VF) switching identically with Pulse Frequency Modulation (PFM) technique is viewed as more beneficial than constant-frequency (CF) switching. Unfortunately, no specific review study observes various control strategies to obtain VF switching on the interleaved converter. This article presents a review of VF switching controls for low-power interleaved converter applications. Also, several issues are discussed related to the interleaved converter control strategy, such as technical challenges and suggested research perspectives. This review is able used as a guide for mapping control strategy based on VF switching research trends.
