This paper presents a review of the most recent module integrated converters (MIC) for PV applications. The MIC topologies are classified in to three main categories: (1) MIC with DC link; (2) MIC with current-unfolding; (3) DC link-less MIC. The study compares various topologies in-depth with respect to efficiency, compactness, reliability, cost effectiveness and ease of implementation. Based on the comparison, several topologies are recommended to be the potential candidates for practical implementation. Simulation is adopted to support the analysis and comparison.
