| Abstract |
The aim of this work is to provide a comparison of power converters operation with analog and digital control. It is desired to look at the respective features in equal conditions. Then the comparison is performed on the same converter, i.e., its operation is evaluated under both analog and digital control. This method provides a reasonable way to establish the convenience in choosing one or another sort of control. Moreover, further generalization of the results is shown through the application of this approach to the main converter structures: controlled converters (implemented with a full bridge thyristor rectifier) and switching converters (with a Cuk converter). The conclusion is centered on the flexibility offered by microprocessor control. The results obtained varing the same control policy implemented with digital or analog technologies on the same converter, as can be expected, are the same. Nevertheless, it is easier to change and prove new policies on a converter with digital control. |
