Autotransformer system reducing total harmonic distortion |
摘要 |
There is disclosed an apparatus and method to reduce total harmonic distortion input into a 24 -pulse autotransformer system and the autotransformer system itself. The 24 -pulse autotransformer system is configured to receive an input of a first voltage and produce an output voltage of a second voltage. The system includes a pair of autotransformers coupled to an AC power source. One winding of each phase of the first autotransformer has a turn ratio to effect a decrease in the voltage across said winding over a symmetric voltage value and a second winding of each phase of the first autotransformer has a turn ratio to effect a decrease in the voltage across said winding over a symmetric voltage value, thereby reducing total harmonic distortion (THD) in the input current to the system without a zero sequence blocking transformer. |
