title = "High Performances Voltage Control of Bidirectional-Asymmetrical DC/DC Converter in Smart Transformer for Limited Reverse Power Flow",
abstract = "The power electronics-based Smart Transformer (ST) can increase the hosting capacity of Distributed Generators (DGs) as well as electric vehicle charging stations and potentially reduce the reinforcements in the distribution grid by providing the DC connectivities and optimizing the capability in the secondary substations. Due to the asynchronous behaviour between the power generation in DGs and load consumption, the ST will operate in asymmetrically bidirectional power flow conditions. The power electronics in the ST can be fully used under the forward power flow condition, while only be partially used under the reverse power flow condition. This paper proposes a Bidirectional-Asymmetrical DC/DC converter in ST to reduce the cost of the power semiconductors and to satisfy the ST operating in bidirectional requirement. Under forward operation mode, the power sharing between two paralleled full bridge rectifiers in the secondary side of the proposed converter is studied and then the output impedance reshaping solution is presented to improve the dynamic performance of the output voltage under load disturbances. The simulation results clearly validate the effectiveness and feasibility of the proposed converter.",
