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.
Experimental results indicate that the inverter performs well under normal grid conditions, weak grid conditions, and grid frequency fluctuations, effectively suppressing the impact of grid voltage disturbances on the system.
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.
The THD should be less than 5% in many grid code standards. The power density of a grid-connected inverter topology systems can be influenced by several factors such as: 1. Converter Topology: The specific converter topology chosen for the grid-connected inverter can impact power density.
Observe the current that is shared on the load by the inverter, and the AC source. Spiking around the zero crossing can occur. These spikes may be mitigated by the user by selecting a different inverter configuration, or using a different modulation scheme. The verification of the grid connected mode of operation is complete.
The increasing penetration of single-phase inverters in distribution networks has raised concerns about grid stability and power quality. Issues such as voltage regulation, harmonic distortion, and protection coordination become more complex as the number of distributed generation units increases.
