Abstract

Hybrid vehicles traditionally rely on separate DC/DC converters for both the battery and fuel cell, which often leads to increased size, higher costs, energy losses, and limited performance. This paper presents an improved solution: a compact, integrated DC/DC converter with a non-isolated, multi-port design. This new approach simplifies the system by combining the fuel cell and battery into a single, unified converter, reducing the typical drawbacks of conventional designs. The proposed converter uses a straightforward topology without the need for bulky transformers, reducing energy losses. It also includes a switched capacitor unit that doubles the voltage output, which helps optimize the power requirements for both the fuel cell and battery under similar load conditions. This design improves the vehicle’s energy management, allowing efficient power distribution and smooth switching between three different operating states. Simulations in MATLAB/Simulink validate the system’s efficiency, demonstrating an expected 10-15% improvement in energy efficiency compared to conventional systems. The compact design also reduces system size and weight, contributing to improved overall vehicle performance. This research explores the converter’s core principles, analyzes its steady-state performance, and outlines a control strategy using proportional-integral control. Simulations demonstrate its effectiveness in supporting hybrid vehicle power needs while simplifying the design.

Keywords: Energy Efficiency, Hybrid Electric Vehicles, Integrated DC-DC Converter, Fuel Cell and Battery Integration, Multiple Operating States.
