What Is the Function of an Inverter?
- Direct current is the simpler, more easily understood current. The current flows in one direction any time a circuit is completed. Direct current also remains at a constant voltage. Batteries, car cigarette lighters and lightning all produce direct current.
- The voltage of alternating current rises and falls like the crests and troughs of a wave. Power companies supply this kind of energy to homes because it is easier to mechanically produce and because it can easily be changed between voltage levels for transfer across high power lines.
- An electrical inverter is a device that converts direct current power to alternating current. Electronics that have the standard, double-pronged plug use alternating current and would need to connect via an inverter if they are to be run on electricity supplied as direct current.
