A DSP based controller for high dynamic bandwidth power electronic applications

Developments in power electronics and control have led to a wide variety of control algorithms for drive and power quality applications. These new control algorithms are computationally intensive and are more practical to implement on microprocessor based controllers. This field of study is still heavily under investigation with many new algorithms being developed. A flexible controller capable of handling these algorithms in real time is therefore necessary. This paper presents such a digital signal processing based controller and implements an active power filter to show the operation of the new controller
