Abstract |
This paper presents a new approach to synchronization for a phase controlled thyristor power converter. Detection of accurate zero crossings are possible even under the following conditions: large frequency change, sudden load changes and large commutation overlap angles. The synchronization is achieved by first reconstructing the reference voltage on the ac source side of the converter transformer. A microcontroller based algorithm is used for this purpose. The reconstructed voltage is subsequently used for synchronization purposes. The improvement provided by the new synchronization scheme is verified experimentally. |
