A power inverter or power invertor, often simply called an inverter or invertor, is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers, which convert AC to DC. Read more on Wikipedia
