Description
Summary:This study explores PWM modulation strategies for interleaved N-cell Boost converters, emphasizing phase angle variation between carriers and operational points, analyzing both Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM). The research shows that equidistant phase shifts minimize input current ripple. Points for ripple reduction and cancellation are identified, demonstrating effectiveness in both modes. The results indicate that optimizing the number of cells and the modulation strategy can significantly reduce current ripple, enhancing the efficiency of renewable energy sources like photovoltaic panels and fuel cells. This approach also reduces the size, cost, and complexity of additional filtering components, offering a robust solution for improving energy conversion systems.
