| Abstract: |
| This paper introduced a soft starter program design method based on anti-parallel circuit of three-phase thyristor which making the start of the asynchronous motor more smooth, at the same time reducing the impact on the grid. The master chip used STM32F103C8T6 micro, and the slopes boost soft starter, current limiting soft starter, discrete frequency soft starter were designed respectively, the key algorithms were also analyzed. The principle of this design is simple, the steps were clear, and it was also easy to program. Finally, the results were given by experiment. |
