Abstract

This paper has designed an active power filter control system with dual digital signal processor (DSP) core, which meets the requirements of functional and intelligent design of the active power filter (APF), and improves the real-time performance efficiency of the controller. Firstly, the structure of the controller hardware system design process, as well as major hardware modules were analyzed in detail; Then in-depth analysis of AD conditioning circuit module, analog-to-digital converter module, dual-port RAM modules and fault detection circuit module as well as the dual DSP program process was introduced. Finally the real-time performance and accuracy of the designed controller was proved by the performance test.
