Heterogeneous Active Power Filter Controller

The paper describes the architecture of a shunt Active Power Filter (APF) controller composed of three components with different characteristics. Heterogeneous components correspond to the variety of tasks expected from the APF controller. Some of the tasks require real-time execution, some of the requirements are specific to the features of general-purpose operating systems, and some require highly responsive timing and precision. The proposed architecture consists of two processors and an FPGA fabric. The processors operate in asymmetric multiprocessing configuration and run respectively real-time kernel and Linux operating system. The presented approach has been successfully applied to APF control.
