| Abstract: | A type of general frequency converter which is suitable for 0. 4 kV/15 kW asynchronous motor is designed based on DSP and CPLD. The structure of hardware and programming idea of software are introduced in detail. Starting Performance of this general frequency converter is analyzed and simulated. It is proven that using compensation voltage can greatly improve the starting performance. Experiment result shows that the general frequency converter can work stably, control the motor intelligently and has good performance of speed regulation. |
