Comparative study of AC/DC converters for More Electric Aircraft

The More Electric Aircraft concept has been seen as the direction of the next generation for aircraft. This paper describes the major concern of the AC/DC converters in the power conditioning system of the aerospace industry. There are many types of AC/DC converter circuits used in aircraft systems. Some of them use transformer rectifier units, passive or active rectifiers with or without a step-up or step-down converter. Their performances versus the power density is an important factor for selection and this paper analyses various circuits for the AC/DC converters used in More Electric Aircraft.
