Abstract

Language:

This paper presents a current control method for a grid-connected partial resonant soft switching inverter that does not utilize an electrolytic capacitor and effectively boosts and bucks voltage. These inverters are essential for integrating distributed energy sources into the power grid. The objective of this study is to analyze and provide design guidelines for closed-loop current regulation in such converters, ensuring compliance with the necessary standards when connecting to the grid. The control methodology is implemented in a synchronous frame, incorporating active damping techniques that utilize feedback from capacitor and inductor voltages to mitigate common resonances at the output. The proposed control strategies were tested on a 400W lab prototype, yielding significant results that validate the effectiveness of the implemented methods in improving grid-connected inverter performance.
