| Abstract: | Digital controllers are the key components of the new injection type hybrid active power filter, and they decide the main functions and indices of the total harmonic eliminating system. The design method and implementation technology of the proposed digital controllers were recommended, which comprised the harmonic detecting method with high accuracy, control arithmetic of variable structure, dead time compensation and hardware implementation. Experimental results verify the reliability of the digital controllers and filtering effect of the new injection type hybrid active power filter. |
