The application of active power filter based on DSP

In order to realize the auto-disturbance rejection control (ADRC) strategy in active power filters (APF), this paper expounds the implementation of the hardware design and control strategy of shunt APF based on DS1104 R&D control board. The intelligent power module (IPM) is taken as the solid-state component of the APF. Then, the overall structure and layout are illustrated in the paper. After that, the technical details of DS1104 are given. The ADRC strategy of the experimental system is realized by MALAB/Simulink. The software of DS1104 can generate the code from the block diagram model automatically and download the code to target hardware directly to implement hardware-in-the-loop(HIL). Experimental results show the feasibility of the hardware. DS1104 provides an easy-use, integrated environment to design quickly without lengthy hand coding and debugging.
