5.01 Inverter Design
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.
