A hybrid interleaved/switched-capacitor boost converter

This paper proposes a boost dc-dc converter topology with the capability of canceling the input current ripple at an arbitrarily preselected duty cycle, high-voltage gain without utilizing extreme values of duty cycle or boosting transformers, it contains a switched-capacitor structure in which the current among capacitors is continuous. The paper provides details on the principle of operation via topological considerations and a mathematical model. The key factor of reactive components sizing is also discussed. The converter was validated in the laboratory through the construction of a hardware prototype.
