Line-commutated inverter
Nettet28. jul. 2024 · The U.S. Department of Energy provides this definition of a line commutated inverter:. An inverter that is tied to a power grid or line. The … Nettetline-commutated inverter. An inverter that is tied to a power grid or line. The commutation of power (conversion from DC to AC) is controlled by the power line, so that, if there is a failure in the power grid, the PV system cannot feed power into the line.
