Essentially, a grid-following inverter works as a current source that synchronizes its output with the grid voltage and frequency and injects or absorbs active or reactive power by controlling its output current. What is a Grid-Following Inverter? Grid-Following Inverters (GFLI) and Grid-Forming Inverters (GFMI) are two basic. This reference design implements single-phase inverter (DC/AC) control using a C2000TM microcontroller (MCU). The design supports two modes of operation for the inverter: a voltage source mode using an output LC filter, and a grid connected mode with an output LCL filter. Specifically, the GFM Droop Control technique, based on the Power–Frequency relationship, is employed. However, as PV penetration increases, conventional controllers encounter.
