| چکیده | ||
| This paper introduces a novel ultra-high-gain DC–DC converter architecture specifically designed for electric vehicle (EV) applications. The converter integrates a switched-capacitor cell with multi-stage inductor–capacitor–two diodes (LC2D) active networks to achieve sequential energy transfer and voltage stacking while maintaining a minimal component count, including only one semiconductor switch. The proposed topology directly addresses the limitations of conventional converters, namely, restricted voltage gains and excessive voltage stress. Simulation results confirm that the converter achieves a voltage gain of up to 10× at a duty cycle of 41.5%, stepping a 45V battery input to a 450V DC bus level typical of EV traction inverters and onboard chargers. The design consistently delivers conversion efficiencies above 95% across a 2-5kW load range, with stable operation, minimal output ripple, and reduced electromagnetic interference. The supported power range aligns with the needs of auxiliary and small-scale EV subsystems. By combining structural simplicity with quantitative performance improvements, the proposed converter offers a compact, reliable, and cost-effective solution for EV powertrains. Overall, the results demonstrate that the converter provides a rigorously validated pathway toward high-gain, high-efficiency DC–DC conversion in EV systems. | ||
