“…Various electrically isolated bidirectional DC-DC topologies have been proposed and studied in recent decades. Among these, the full-bridge phase-shift (FBPS) converter is an isolated DC-DC converter with good wide voltage regulation characteristics [10,11], but its lack of soft switching in the main circuit under light load reduces its efficiency. In addition, its topology is asymmetrical because the filter inductors are placed on the secondary side.…”

This paper presents a new control method for a bidirectional DC–DC LLC resonant topology converter. The proposed converter can be applied to power the conversion between an energy storage system and a DC bus in a DC microgrid or bidirectional power flow conversion between vehicle-to-grid (V2G) behavior and grid-to-vehicle (G2V) behavior. Furthermore, such a converter can be applied to energy storage systems for decentralized renewable energy generation systems, such as solar and wind power. In addition, this converter can be combined with a bidirectional inverter to allow energy storage in the system to improve the safety, stability, and power quality of the microgrid. In the proposed circuit structure, we use a bidirectional DC–DC LLC, which has the advantages of a higher voltage conversion ratio, lower part count, simpler control than similar converters such as DAB, CLLC, and L–LLC converters, and bidirectional power flow and electrical isolation. Specifically, to extend the battery life, it can be employed as a control strategy for discharging the energy stored in the battery (SOC) and reducing the temperature rise generated by the internal solid electrolyte interphase (SEI) when discharging the battery under the variation in distributed energy resource (DER) generation and load demand. To realize the bidirectional power conversion without using any auxiliary inductor and only changing the control strategy, the forward step-down power conversion was based on pulse frequency modulation (PFM) control, and the reverse step-up power conversion was based on pulse width modulation (PWM) control. In this paper, we introduce the bidirectional converter topology and its control strategy for the DC microgrid battery energy storage system. Finally, a 500 W prototype is built to verify the effectiveness of the proposed converter.

“…As for research studies revolving around converters, a full-bridge converter (FBC) for bidirectional power transfer is presented in [14]. The proposed FBC is an isolated DC-DC bidirectional converter, linked to a double voltage source-a voltage bus on one side, and a stack of super-capacitors (SOSC) on the other side and real prototype, compliant with automotive applications.…”
