【 摘 要 】
This paper proposes a family of high-voltage-gain step-up dc-dc converters for photovoltaic integration application. The proposed converters are capable of converting the low voltage from input sources to a dc bus. The proposed family is constructed of interleaved single-switch multistage boost converters and voltage multiplier cells (VMC). The proposed converters feature low voltage stress across the components, equal current sharing among all phases, and a smooth input current. Moreover, the proposed family of converters has a modular structure in both the VMC and the boost stage. That is, the VMC can have N number of cells, and the boost stage can have k number of stages. The k can be different in each phase, allowing the designers to integrate two independent renewable energy sources with different output voltages. An example converter was explained, analyzed, and simulated. An 80 W hardware prototype was implemented to confirm the converter’s operation and validate the analysis.
