This paper presents a new five-level rectifier structure which is compared with a well known solution. Flying capacitor and coupled inductor concepts are used and discussed for the two structures. Control strategies and simulation results are presented in order to show the operation mode and performances of each structure. Advantages and disadvantages are presented in view of the total power losses in the semiconductor devices, the maximum output power and the type of application where these converters are best suited.
