Abstract
This paper introduces a novel non-isolated boost DC-DC converter employing the voltage-lift technique to address limitations of conventional designs. The proposed topology, comprising two switches, two inductors, three capacitors, and three diodes, achieves high voltage gain, reduces current ripple, and minimizes component stress while maintaining simplicity and cost-effectiveness. Detailed analyses in continuous current mode (CCM) explore the voltage gain characteristics and identify the conditions for stable operation. Switch current stress is examined, and critical inductance requirements are determined. A notable feature of the converter is that the voltage across the main switch remains lower than the output voltage, enhancing its operational efficiency. Validation through PSCAD/EMTDC simulations and experimental results confirm an efficiency of 96%. These findings highlight the converter’s suitability for high-performance applications in renewable energy systems, electric vehicles, and other advanced power conversion scenarios.
