论文摘要
局部共振高频链路转换器被认为提供了软开关的单阶段功率转换。由于消除了直流电容器，它们非常可靠。先前的工作集中在概念拓扑和设计要求上。在这项工作中，提出了当前来自该转换器家族的AC-DC转换器。讨论了控制设计和网格集成要求。实现了使用网格电流反馈的活动阻尼方法，以减轻过滤器共振振荡。当前控件使用面向电压的控制在同步框架中实现，从而实现功率因数和功率流控制。转换器操作及其控制回路表演的结果显示
Partial resonance high frequency AC link converters are recognized to provide soft-switching, single-stage power conversion. They are highly reliable due to elimination of DC capacitors. Previous work has focused on proof of concept topologies and design requirements. In this work, a current regulated AC-DC converter from this family of converters is presented. The control design and grid integration requirements are discussed. An active damping method using grid current feedback is implemented to mitigate the filter resonance oscillations. The current control is implemented in the synchronous frame using voltage oriented control which enable power factor and power flow control. The result of converter operation and its control loops performances are presented
