This paper presents a new multiple-input soft-switching DC−DC Ćuk converter for clean and renewable energy sources. The proposed converter can buck and boost the different voltages of renewable energy sources to produce a constant DC output voltage in a DC microgrid. In the proposed converter, edge-resonant soft-switching modules are used to perform better than the conventional multiple-input Ćuk converter. All switches in the edge-resonant soft-switching modules can realize zero-current switching turnon and zero-voltage switching turn-off. By using these modules, the proposed converter can achieve lower current stress of the switches, wider soft-switching range, and higher power efficiency than the conventional multiple-input Ćuk converter. These advantages are achieved in the edge-resonant modules, which optimize soft-switching states and costs. In addition, the soft-switching states can be easily achieved because the edge-resonant soft-switching modules have a wide soft-switching range. Furthermore, the proposed converter can independently transfer the generated power from renewable energy sources to the DC microgrid. In this article, the operation principles and performance of the proposed converter are discussed in detail. The theoretical analysis is validated by experimental results obtained from a laboratoryscale prototype and full-scale real-time hardware-in-the-loop experiments.INDEX TERMS DC−DC power converters, Edge-resonant, Multiple-input Ćuk converter, Zero-current switching, Zero-voltage switching.

This research presents a non-isolated multi-port power converter feasible to hybridize energy alternatives in electric vehicles. Due to the hybridization of the various input sources, there are several advantages in load power distribution in the system. Flexible control of discharging as well as the charging process concerning the energy sources can be achieved. The developed converter can able to boost the voltage levels with dual inputs such as a renewable solar PV and the other input as a battery and provides dual outputs with various voltage levels, which can able to suit the converter fed for several loads like motor drive and the low-rated loads like lighting and other auxiliary supplies in electric vehicles. Also, as the various voltages appear at the output, this converter can be interfaced with multilevel inverters fed electric vehicle drivetrain. The utilization of multilevel inverters reduces the total harmonic distortion and torque ripples in motor drives in electric vehicles. The proposed converter consists of less number of components making the circuit simple and cost-effective. With one inductor, two various modes are obtained for charging and discharging states concerning the energy storage units. A state-space analysis is designed for all the converter operating modes along with its control design. The proposed multi-port DC-DC converter is designed in MATLAB/Simulink and tested in a laboratory environment with a hardware setup.INDEX TERMS Multi-port DC-DC converters, hybrid energy storage system, state-space modeling, electric vehicles.

SummaryMulti‐input converters (MICs) play a significant role in the aspect of the integration of sources. The reliability of the converter can be enhanced by using a suitable fault tolerance converter design and control algorithm. A dual‐input single‐output (DISO) DC–DC converter with source fault tolerance is proposed in this paper. In the literature, there are many topologies in this area of work; however, most of them are based on time‐sharing control. In this control scheme, one input source is contributed to the load, and others are kept idle in a particular duty interval; hence, this control scheme leads to underutilization of the converter. The proposed converter is designed to circumvent these challenges and can produce boost, buck–boost, and buck operations. And also, it has a source fault feature for achieving the preserved output voltage under source V1 or V2 failure conditions. A 200‐W prototype is designed, and the feasibility of the proposed converter is validated through simulation and experimental results.
