A power inverter is an electrical power converter that changes direct current (DC) to alternating current (AC). The converted AC current can be produced at any required voltage and frequency with the use of appropriate transformers, switching and control circuits. A common use of an inverter is in a solar energy installation. Solid-state inverters have no moving parts and are used in a wide range of applications, from small switching power supplies in computers, to large electric utility high-voltage direct current applications that transport bulk power.
