Abstract
Abstract This paper proposes a novel non-isolated multi-input dc-dc boost converter for electrical vehicle application. A hybrid system balances the power of the system by using two or more sources. The power between the input sources can be flexibly distributed without any distortion. The charging or discharging of the energy storage systems by other input energy sources can also be monitored in a proper manner and is a feasible task. The design consists of only one inductor and the charging and discharging of the energy storage system decides the operation modes of the converter. In this paper, every operating mode has a small signal model that leads to the control system design for the converter. Simulation and experimental results are provided to prove the validity of the converter and the performance of its control system.
