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.

Significantly, the performance of a grid-independent hybrid electric vehicle (GIHEV) is decided by a multi-input converter in it. This paper discusses the detailed mathematical modeling, design, prototype validation, and analysis of a multi-input DC-DC converter (MIC). This converter actively accommodates fuel cell and solar photovoltaic (PV) panel as sources and utilizes the concept of multiple switching frequencies to get wide regulation of output voltage and power flow. The average large-signal modeling, small-signal modeling, and steady-state modeling are demonstrated to achieve accurate design and analysis. The reliability analysis of the proposed converter along with the respective mathematical background is discussed. The proposed system design is validated with the help of an experimental setup and tested effectively. The proposed converter promises higher gain and 95.58% efficiency with fewer switches, low voltage stress, and fewer circuit components.

“…The two-way communication between the EV and the grid is referred to as vehicle-to-grid technology. EVs and PHEVs can have various benefits in this application, such as regulating the peak power and shifting the peak load (Bassa de los Mozos et al , 2019; Benavides and Chapman, 2008; Guo et al , 2020; Khasim and Dhanamjayulu, 2021). The increased use of battery-powered EVs has increased the need for power generation (Lipu et al , 2021).…”

Purpose This study aims to present a modified interleaved boost converter (MIBC) topology for improving the reliability and efficiency of power electronic systems. Design/methodology/approach The MIBC topology was implemented with two parallel converters, operated with a −180 degree phase shift. Using this methodology, ripples are reduced. The state-space model was analysed with a two-switch MIBC for different modes of operation. The simulation was carried out and validated using a hardware prototype. Findings The performance of the proposed MIBC shows better output voltage, current and power than the interleaved boost converter (IBC) for the solar PV array. The output power of the proposed converter is 1.353 times higher than that of existing converters, such as boost converter (BC) and IBC. The output power of the four-phase IBC is 30 kW, whereas that of the proposed two-phase MIBC is 40.59 kW. The efficiency of MIBC was better than that of IBC (87.01%). By incorporating interleaved techniques, the total inductor current is reduced by 29.60% compared with the existing converter. Practical implications The proposed MIBC can be used in a grid-connected system with an inverter circuit for DC-to-AC conversion, electric vehicle speed control, power factor correction circuit, high-efficiency converters and battery chargers. Originality/value The work presented in this paper is a modified version of IBC. This modified MIBC was modelled using the state-space approach. Furthermore, the state-space model of a two-phase MIBC was implemented using a Simulink model, and the same was validated using a hardware setup.
