Contact UsIn these applications, a grid- connected voltage source inverter (VSI) to supply the power to the mains grids attracts numerous studies on the control strategies to provide a high quality of grid-injected current even under non-ideal grid voltage environment.
Grid-Following Inverters (GFLI) and Grid-Forming Inverters (GFMI) are two basic categories of grid-connected inverters. 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.
The control design of this type of inverter may be challenging as several algorithms are required to run the inverter. This reference design uses the C2000 microcontroller (MCU) family of devices to implement control of a grid connected inverter with output current control.
In contrast, a grid-forming inverter works as a voltage source that sets the amplitude and frequency of the grid, as introduced in Grid-Forming Inverter.
In the research work (Jorge, Solsona, and Busada, 2014), a grid voltage-sensorless current control scheme which is unaffected by grid frequency variation is presented to produce high quality of injection current under distorted grid conditions. However, this approach is applied for an L-filtered grid-connected inverter.
Do not leave the design powered when unattended. Grid connected inverters (GCI) are commonly used in applications such as photovoltaic inverters to generate a regulated AC current to feed into the grid. The control design of this type of inverter may be challenging as several algorithms are required to run the inverter.
