Technical FAQs 4

Are 'balanced' grid voltages considered in current ripple analysis?

Focusing solely on grid-connected applications, ‘balanced’ grid voltages have been considered in the current ripple analysis for both phase and neutral findings. Due to small ac coupling reactance (usually 0.05–0.08 p.u.), relevant unbalanced currents can be driven by slightly asymmetric inverter voltages.

What is the control design of a grid connected inverter?

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.

Can a grid connected inverter be left unattended?

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.

How do I know if a grid connected inverter is working?

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.
