Latest Patents

Sung Yeul Park holds a patent for a "Control system and method for a universal power conditioning system." This invention proposes a new current loop control system method for a single-phase grid-tie power conditioning system that can operate in both standalone and grid-tie modes. The inverter utilizes an inductor-capacitor-inductor (LCL) filter as the interface between the inverter and the utility grid. The design allows for flexibility, using an LC filter in standalone mode and the complete LCL for grid-tie mode. A novel admittance compensation technique is introduced to enhance controller design, ensuring stability while maintaining sufficient gain at the fundamental frequency. Simulation results demonstrate that the proposed system effectively mitigates issues related to undesired admittance paths, leading to improved performance.
