Technical FAQs 4

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.

How does an inverter convert DC to AC?

Fundamentally, an inverter accomplishes the DC-to-AC conversion by switching the direction of a DC input back and forth very rapidly. As a result, a DC input becomes an AC output. In addition, filters and other electronics can be used to produce a voltage that varies as a clean, repeating sine wave that can be injected into the power grid.

How do inverters provide grid services?

In order to provide grid services, inverters need to have sources of power that they can control. This could be either generation, such as a solar panel that is currently producing electricity, or storage, like a battery system that can be used to provide power that was previously stored.

Is a DC-AC converter suitable for grid-connected PV arrays?

This paper presented a low-cost and low-power single-phase power DC-AC converter for grid-connected PV arrays and its control strategy. The topology is based on a boost-buck converter and an unfolding inverter interfaced with the power grid, allowing high power density.
