“…Regulating the duty cycle by the PI controller improve the soft-switching performance of the converter. The application of PPS control strategy can be extended to a wider group of bidirectional converter [109]. The experiment result shows that the proposed control technique is suitable for an energy storage system with a wide voltage range and high efficiency.…”

Bidirectional DC-DC power converters are increasingly employed in diverse applications whereby power flow in both forward and reverse directions are required. These include but not limited to energy storage systems, uninterruptable power supplies, electric vehicles, and renewable energy systems, to name a few. This paper aims to review these converters from the point of view of topology as well as control schemes. From the point of view of topology, these converters are divided into two main categories, namely non-isolated and isolated configurations. Each category is divided into eight groups along with their respective schematics and a table of summary. Furthermore, the common control schemes and switching strategies for these converters are also reviewed. Some of the control schemes are typically applied to all DC-DC power converters such as PID, sliding mode, fuzzy, model predictive, digital control, etc. In this context, it should be noted that some switching strategies were designed specifically for isolated bidirectional DC-DC converters in order to improve their performance such as single phase shift, dual phase shift, triple phase shift, etc. The features of each topology and control scheme along with their typical applications are discussed, in order to provide a ground of comparison for realizing new configurations or finding the appropriate converter for the specific application.INDEX TERMS Batteries, bidirectional power flow, control systems, dc-dc power converters. 5) CASCADED BIDIRECTIONAL DC-DC CONVERTER [19], [20] 4) FORWARD BIDIRECTIONAL DC-DC CONVERTER [35]-[39]

“…A high voltage gain of DC-DC converters can be achieved through various configurations, e.g., the push-pull [3], halfbridge [4], full-bridge [5] and voltage multiplier cells [6], which requires high frequency transformers. Moreover, the coupledinductor technique is an alternative to achieve high voltage gains using less components [7], [8].…”

This paper explores the coupled-inductor architectures for a trans-inverse DC-DC converter. The parasitics (e.g., leakage inductance and AC resistance) will inevitably affect the performance of the coupled-inductor and thus, the entire system. More specifically, when ignoring these parasitics, the operation principle of the DC-DC converter changes and the boosting capability is degraded. Considering the application in a trans-inverse DC-DC converter, three winding arrangements are explored in detail to demonstrate their advantages and disadvantages. Finite element analysis (FEA) on the magnetics is conducted in this paper to simulate the leakage inductance and AC resistance. Finally, the performance of the trans-inverse converter with the designed winding arrangements is verified by experimental tests.

This study proposes a family of duty-cycle controlled bidirectional resonant converters and its uniform modulation schemes. This family of converters is composed of a current-fed stage, a transformer with LC resonant tank and a voltage-fed stage. Therefore, high-voltage gain and low-current ripple can be achieved. With the proposed uniform modulation schemes, automatic forward and backward mode transition is realised. Furthermore, the voltage gain is only determined by the duty cycle, independent of load and power flow direction, thus simple control can be adopted and voltage can be regulated in a wide range. Zero-voltage switching of all switches can be achieved over a wide load range. The operation principle and analysis of one of the converters are presented as an example. Design considerations are provided. Experimental results are shown to verify the theoretical analysis.
