论文摘要
本文介绍了网格连接的部分共振软开关逆变器的当前控制方法。该逆变器不使用电解电容器，并且能够增强和逆转电压。网格连接的逆变器用于将分布式能源集成到网格中。当前的控制对于满足连接到电网时的标准和要求至关重要。分析了此类转换器的闭环电流调节，并提供了设计指南。控件在同步框架中实现。另外，使用电容器电压和电感器电压反馈的主动阻尼技术用于减轻输出处的CL滤波器共振。提到的控制策略是在400W实验室原型上实施的，结果将显示
This paper presents current control method for a grid-connected partial resonant soft switching inverter. This inverter does not use an electrolytic capacitor and is capable of boosting and bucking the voltage. Grid-connected inverters are used to integrate distributed energy sources to the grid. Current control is vital in meeting the standards and requirements when connecting to the grid. The closed-loop current regulation for this type of converters is analyzed and design guidelines are provided. The control is implemented in the synchronous frame. In addition active damping techniques using capacitor voltage and inductor voltage feedback is used to mitigate CL filter resonance at the output. The mentioned control strategies are implemented on a 400W lab prototype and the results are presented
