What does the word inverter mean?
The term inverter refers to the ability to change DC power into AC. Inverter power supplies immediately rectify the
incoming AC to DC, and then the transistors create a higher frequency AC. The higher frequency AC then goes on
to a much smaller main transformer than in a conventional power supply. The AC is then rectified to extremely
smooth DC. The diagram to the below shows the basic electrical wiring of a DC output inverter power supply.
