Abstract

This work addresses transfer efficiency and tracking ineffectiveness in switch-mode, dc-dc converters for photovoltaic energy-conversion systems. Tracking ineffectiveness constrains maximum power point tracking algorithms due to dc-dc converter operational constraints. Transfer efficiency quantifies the effect of switching-frequency ripple on the usable power extracted from the photovoltaic source. A dual-stage boost buck-boost converter is proposed as a solution to alleviate tracking ineffectiveness and enhance transfer efficiency. Simulations and experimental results indicate that both concerns are addressed by the proposed topology.
