This article discusses an extension of the hybrid-frequency parallel inverter system belonging to wide-bandgap/silicon hybrid family. The system consists of two inverters connected in parallel, with the low-frequency high-power inverter achieving high power output and the high-frequency low-power inverter improving output current quality through ripple attenuation. The article presents the design and implementation of a three-phase three-wire topology and introduces ripple compensation models and a wireless carrier synchronization algorithm.
In this article, an extension of the hybrid-frequency parallel inverter system (HbFPIS) belonging to wide-bandgap/silicon (WBG/Si) hybrid family is discussed. HbFPIS contains two inverters connected in parallel, each having a specific function. The low-frequency high-power inverter's primary function is to achieve high power output with low-frequency modulation. The high-frequency low-power inverter, having a high dynamic response, is used to improve output current quality by ripple attenuation. In this article, three-phase three-wire (3P3W) HbFPIS topology is designed and implemented. The ripple compensation in 3P3W HbFPIS topology involves ripple models presented in this article. A wireless carrier synchronization algorithm based on ripple modeling is implemented, resulting in autonomy and increased reliability of the parallel modules. Simulated and experimental results from 20-kVA grid-connected 3P3W HbFPIS have confirmed the analysis and discussion.
