What is a DC-AC converter?
A DC-AC converter is commonly called an "inverter." It is an electronic device for converting direct current (DC) to alternating current (AC).
Inverters are used in a wide range of applications, from small switched power supplies for a computer to large electric utility applications to transport bulk power.
