“…Since the TPCs proposed in this paper and [24] show many common advantages, Table II further shows the count of bootstrap drivers, the control strategies, the circulating current, and the operation region of the two TPCs under the same conditions. As can be seen, all switches of the TPC in [24] can realize soft-switching, hence the switching frequency can be set higher to optimize the sizes of the passive components.…”

This paper proposes a high gain transformer-less three-port converter (TPC) for standalone photovoltaic (PV) systems. The TPC is designed and developed based on a dualinductor high gain two-port converter by utilizing one of the buffer capacitors to derive the third part for PV input. A hybrid pulse frequency modulation (PFM) scheme unified with a pulse width modulation (PWM) control strategy is adopted, which realizes the maximum power point tracking (MPPT) control, load voltage regulation, and bidirectional energy flow at the battery port. The proposed TPC offers the unique advantages of high voltage gain, continuous battery port current, reduced power semiconductors, lower voltage stresses, the common ground shared by all ports, low-cost gate driver, and small size of the rear-end inductor. The working principle, steady-state characteristics, small signal models and control method, including design conditions, are comprehensively analyzed. The correctness of the theoretical analysis is verified by developing a 300W experimental prototype, which shows the maximum efficiency is 97.7%.

In recent years, Electric Vehicles are becoming more popular. The pollution level in the atmosphere can be effectively minimized by using Electric vehicles for large-scale transportation. A battery station is required for continuous operation; however, the Photovoltaic-based OFF grid charging station can only operate during the day. Therefore, the three-port converters have started to arise from a number of current EV charging station developments. In this study, a unique PWM and Phase Shift Controller are proposed to reduce switching losses and to improve reliability. In addition, for Maximum PowerPoint Tracking, a Fuzzy is added to the PV system. Furthermore, an appropriate interleaved boost converter topology is used to create the various charging voltages required for EV and battery stations. The proposed topology is simulated, and the hardware prototype has been created and tested. The result shows that the proposed topology has a better efficiency than the traditional converters.Article Highlights. A dual composite charging station for electric vehicle charging in environment friendly manner. Optimization of power electronics required in Electric Vehicle charging stations. Maximum utilization of battery for cyclic charging from charger and discharging through Electric Vehicles.
