| Abstract |
An improved method of current reference dctennination for a three-phase parallel active power filter is presented. Besides the response of filter current reference to the load
current change, synchronization to the network is considered. To avoid usual problems with synchronization relying upon line voltage zero-cross detection, a new approach with line voltage fundamental hannonic calculation is applied. Theoretical basis of the idea is proven and results of the corresponding tests with a three-phase parallel active power filter are shown. All processing tasks are perfonned by a 32-bit microcontroller, which controls filter's power stage, based on time-discrete triggering principle. |
