Abstract: Beacuse the conventional approaches for passive power filters design depend on experiences too much and they are lack of ability for optimization and the difficulty of APF designing, a shunt active power filter(SAPF) digital control system based on TMS320LF2407A was adopted based on instantaneous reactive power theory. The working theory and the system structure of active power filter were introduced in the first. And the designing strategy of how to use TMS320LF2407A researching SAPF, including hardware and software,was discussed. The experiment indicate that this approach is correct and efficiency and the digital control system is worth to generalizing.
Key words: active power filter (APF); harmonic compensation; digital signal processing (DSP); digital control
