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 this section, the proposed converter is compared with other three‐port converters in the literature. The capabilities of bidirectional power flow, individual or simultaneous power transfer of sources, number of used components (switch, diode, inductor and capacitor), capabilities of voltage step‐up, PVS on semiconductors etc., are selected as comparison factors and listed in Table 3 Among the structures presented in the table, only the structure in [15, 22, 23, 27] and the proposed converter have bidirectional power flow capability, which is one of the most important advantages of the proposed structure.…”

“…The converter in [21] is another MI converter with high step-up and soft-switching capabilities in which the bidirectional power flow is not provided. A three-port bidirectional DC-DC converter presented in [22] integrates a PV panel and a battery in a DC nanogrid. The most important disadvantage of this converter is the lack of common ground between the ports.…”

The proposed converter here is a dual-input DC-DC converter with bidirectional power flow. One of the inputs is unidirectional, while the other is a bidirectional port for a battery. The proposed converter can combine two alternating sources with different characteristics. The demanded power of the load can be provided by each input source individually or simultaneously. What is more, the unidirectional port can charge the battery as well as power the output load. Due to the bidirectional capability, the energy returned from the output can be stored in the battery which is suitable for electric vehicle (EV) applications.Step-up capability, the low voltage stress on semiconductors, and the smaller number of passive elements are the other advantages of the converter. Depending on the battery usage status, four different operation scenarios are defined in the proposed converter. The converter operation is described in each scenario and the mathematical analysis is presented. Based on these, the experimental prototype is conducted to verify the characteristics and feasibilities of the converter.
