What are inverters?

An inverter is a power electronics device used to generate alternating voltages and currents from a source of direct electrical energy. Its operation is to be dissociated from other converters such as AC/AC converters, rectifiers or even DC/DC converters.

Inverters are just one example of a class of devices called power electronics that regulate the flow of electrical power. 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.
