The inverter acts as the bridge, converting DC → AC. . Inverter Definition: An inverter is defined as a power electronics device that converts DC voltage into AC voltage, crucial for household and industrial applications. DC is the type of current that flows in one direction, typically produced by batteries, solar panels, and other sources. [1] The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large. . They work by converting the power obtained from the DC source, which is the input source of the inverter, into AC, which is the output source of the inverter, and then distributing it to various devices that require AC sources.
