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.
Simulation and experimental results show that the grid current harmonics are effectively suppressed with the proposed inverter. Its efficiency can be higher than that of the L-type inverter and LCL-type inverter.
Main contributions are summarized as follows. A unified admittance model of the LCL -type grid-connected inverter is developed for inverter-side and grid-side current control to facilitate the passivity-based stability analysis and the study of the effect of control delay and CVF-AD on the passivity properties of inverter output admittance.
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.
