چکیده
This paper presents a novel transformerless dual-stacked boost DC-DC converter integrated with voltage multiplier cells (VMCs), specifically designed to address the ultra-high voltage gain requirement in PV applications. The proposed structure achieves an exceptionally high voltage conversion ratio using a moderate duty cycle while ensuring low voltage stress on the main power switches. The converter's operation and performance were validated through comprehensive simulation studies conducted at a switching frequency (fs) of 50 kHz. Open-loop simulations confirmed the static gain capability, demonstrating a voltage gain of 16 times by boosting a 20 V input to an output of approximately 320 V at a duty cycle of 50%. Furthermore, the converter’s dynamic performance was rigorously assessed in a closed-loop environment by integrating it with a PV array and an MPPT controller. This setup confirmed the ability to regulate the DC bus voltage at 380 V while effectively tracking the Maximum Power Point (MPP). The results confirm that the proposed converter provides a structurally simple and highly effective solution for high-gain power conversion in renewable energy systems.
