“…There have also been many reports on bidirectional isolated DC-DC converters with a voltage-fed inverter connected on the high-voltage side and a current-fed inverter connected on the low-voltage side [3][4][5][6][7][8][9]. However, when such inverters are operated in the buck mode to supply power from the high-voltage side to the low-voltage side, the transformer's low-voltage winding must have more turns to obtain sufficient output power, even at low input voltages.…”

SUMMARYThis paper proposes a bidirectional isolated DC-DC converter with an active clamp circuit and two novel control methods in the buck mode. A circulating current reduction method decreases the conduction loss. A commutation overlap period reduction method maintains the output power by expanding the maximum actual duty cycle even if the input voltage decreases. The experimental results show that the proposed method increased the maximum output 1.5 times, without increasing the voltage applied to the lowvoltage side MOSFETs under the minimum input voltage condition. A 2-kW class prototype showed a higher than 90% efficiency over a wide operating range for a greater than 20 input-output voltage ratio at 100-kHz switching frequency. C⃝

“…A fullbridge bidirectional dc-dc converter can be used for high power application. Various bidirectional isolated full-bridge based topologies have been published in the literatures with reduced switching loss, improved EMI and increased efficiency [8][9][10][11]. Moreover the bidirectional isolated dc-dc converter has the advantage of galvanic isolation.…”

A photovoltaic (PV) system has a variable power output that depends on solar irradiance level and ambient temperature. This will be an issue when there is a massive penetration of PV in the future. Therefore, an energy storage system is indispensable to compensate the problem of PV output fluctuations. Battery energy storage system (BESS) employing power electronic converters can be used for compensating the fluctuating PV power. This paper proposes a 2-kW full-bridge bidirectional isolated dc-dc converter that is employed in a BESS with PWM converter for PV output power leveling. This paper also presents a current controller using the DQ synchronous reference frame for regulating voltage at the high-voltage dc side, and a bidirectional power flow control for controlling the output power of the BESS to ensure that the power that is injected to the point of common coupling (PCC) is leveled at 2 kW. The performance of the system is confirmed with PSCAD simulation.Keywords-Bidirectional isolated dc-dc converters, energy storage systems, photovoltaic (PV) output power leveling, battery energy storage system (BESS), point of common coupling (PCC).

Modelling of bidirectional full bridge DC-DC converter as one of the most applicable converters has received significant attention. Mathematical modelling reduces the simulation time in comparison with detailed circuit response; moreover it is convenient for controller design purpose. Due to simple and effective methodology, average state space is the most common method among the modelling methods. In this paper a bidirectional full bridge converter is modelled by average state space and for each mode of operations a controller is designed. Attained mathematical model results are in a close agreement with detailed circuit simulation.
