Abstract

This paper proposes a step-up DC-DC converter for a power electronic circuit for standalone photovoltaic systems with battery energy storages. The proposed DC-DC converter effectively converts low DC battery voltage into high DC-link voltage. It operates with soft-switching characteristics, which can reduce switching power losses. The proposed converter operates without output voltage feedback, which simplifies its control design. The operation principle of the proposed converter was described, along with the overall system configuration. The experimental results were discussed for the 500-W prototype system using a 12-V lead-acid battery.
