An inverter is a power electronic device 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 were originally large electromechanical devices converting AC to DC. Circuits that perform the opposite function, converting AC to DC, are called rectifiers. The runtime of an inverter powered by batteries is dependent on the battery power and the amount of power being drawn from the inverter at a given time.
