Abstract
This paper introduces a non-isolated single-input dual-output (SIDO) multiport DC-DC converter with applications in renewable energy systems, electric vehicles, uninterruptible power supplies, battery chargers, and personal computers. The proposed SIDO converter consists of two independent outputs, regulated at 110 V (as a boost stage) and 12 V (as a buck stage), respectively. Key features include an optimal 12-component count, continuous input currents, a common-ground architecture, and independent controllability of output voltages. Furthermore, the converter achieves the desired voltage gain, low voltage stress on diodes and switches, and a high efficiency of approximately 93.1%. The system is designed for a 245.77 W total power rating, providing 132.5 W for the boost stage and 113.3 W for the buck stage. The proposed topology is tested in the laboratory, and the experimental results verify the proper performance of the converter.
