چکیده :

The rapid growth of electric transportation has intensified the demand for compact and efficient power conversion systems capable of delivering large voltage gains from low-voltage supplies. In this work, a new non-isolated converter topology is introduced, employing a hybrid combination of inductive and capacitive components arranged to maximize boosting capability. The architecture utilizes two independent duty ratios, allowing wide control flexibility and significant voltage enhancement without resorting to extreme switching operation. Unlike conventional transformer-based solutions, the proposed design minimizes voltage stress on the semiconductor devices and reduces the overall size of passive elements. Analytical derivations confirm the controllable gain characteristics of the system, which makes it well-suited for vehicle applications where both high efficiency and reliability are crucial. Simulation results and theoretical analysis verify the feasibility of the converter and demonstrate its potential for integration into advanced electric vehicle powertrain systems.
